Answers & Explanations

1. C: The formula for simple interest is I = Prt, where I represents the interest amount, P represents the principal, r represents the rate, and t represents the length of time. Substituting 600 for I, 2500 for P, and 0.06 for r gives: 600 = 2500(0.06)t. Solving for t gives t = 4. So, she will have to wait 4 years for her principal to earn $600 in interest.

2. D: If she only takes out 12 jellybeans, blue jellybeans may remain in her pocket. However, is she takes out 13 jellybeans, she is ensured that one of each color will have been taken out.

3. A: Solving the first equation for Z gives r/5=Z. Substituting this value of Z into the second equation gives 15(r/5)=3y, which simplifies to 3r = 3y. Dividing both sides of the equation by 3 gives r = y.

4. C: The second part of the problem may be modeled with the equation, 12 = 0.15x. Dividing both sides of the equation by 0.15 gives x = 80. 35% of 80 may be written as 0.35(80), which equals 28.

5. C: The problem may be modeled with the equation, x - 0.20x = 1600, which simplifies to 0.80x = 1600. Dividing both sides of the equation by 0.80 gives x = 2000. The original cost of the computer was $2000.

6. B: The cost of the SUV to the dealer may be represented by the equation, 39000 = x + 0.25x, which simplifies to 39000 = 1.25x. Dividing both sides of the equation by 1.25 gives x = 31,200.

7. E: The problem may be modeled by the expression, 49000 - 0.20(49000), which equals 39,200. Thus, he sold the car for $39,200.

8. B: The problem may be modeled with the equation, 1/4+1/6+1/2=1/t, which simplifies to 11/12=1/t. Solving for t gives t=12/11. Thus, they can finish the work in 1.09 days, when working together.

9. D: The quotient of 12 divided by 12 is 1. The quotient of 0.12 divided by 12 equals 0.01, since the decimal point in 0.12 is moved two places to the left.

10. D: When dividing terms, with the same base, the exponents should be subtracted. So, x5/x2 =x3.

11. B: The integer, 1, is a natural number. The natural numbers are a subset of the set of whole numbers, and the set of whole numbers are a subset of the set of rational numbers. Thus, the integer, 1, is a natural number, whole number, and rational number.

12. C: 4 occurs in the list three times, which is more than any other frequency, thus it is the mode.

13. D: This set contains the element, 0, which would result in division by zero.

14. C: The number of cups of sugar she needs is equal to the sum of 3/8 and 3/5, or 39/40. The amount of sugar she has and the amount she needs may be compared by finding a common denominator. Doing so gives the fractions, 78/80 and 75/80, showing that she needs 3/80 cup more of sugar.

15. B: The attendance of employees and their spouses may be modeled by the expression, 1/2+1/3, which equals 5/6. Thus, 1/6, or 16.7%, of the attendees were not employees or spouses.

16. C: The GPA may be represented as ((2.3)+(3.2)+(4.4)+(3.4))/13, which is approximately 3.08.

17. D: The problem may be modeled by the proportion, 8/(1/2)=x/(7 3/4). Solving for x gives x = 124. Thus, there are 124 ounces in 7 3/4 pounds.

18. E: Tripling X and Y gives 3XZ/3Y, which reduces to XZ/Y, which is the same as the given fraction.

19. E: The pattern is a geometric sequence, with a common ratio of 1/2. Multiplication of 1/8 by 1/2 gives 1/16, or the next number in the pattern.

20. B: Liters is the most reasonable measurement for capacity of water in a bathtub.

21. D: The proportion, 0.17/x=1/12, may be used to find the length, in inches. Thus, the length of the match box is 2.04 inches. The length of 2 3/16 is closest to this length.

22. B: 1/200=0.005, which equals 0.5%.

23. C: Movement of 4 units to the left and 5 units up gives the ordered pair, (6, 8). Note. 4 is subtracted from the x-value of 10 and 5 is added to the y-value of 3.

24. A: The average may be written as 28.49/7, which equals 4.07. Thus, his average cost per day was $4.07.

25. E: The unit of cups is the most reasonable measurement for measuring the capacity of sugar.

26. C: The inequality may be written as 42 > x ≥ 40. A length of 3 3/8 feet equals 40.5 inches, which satisfies the required conditions of the inequality.

27. D: The problem may be modeled with the expression, 750 + 0.15(750), which equals 862.50. Thus, his asking price would be $862.50.

28. A: The ratio, 300/x, represents the number of jellybeans purchased for x dollars. Since 50 cents is one-half of a dollar, the ratio, 150/x, will represent the number of jellybeans that may be purchased at the same rate.

29. B: The first part of the problem may be modeled with the equation, 6 = 0.24x, where x represents the number to be determined. Solving for x gives x = 25. 40% of 25 is written as 0.40(25), which equals 10.

30. B: The following proportion may be written and solved for x: 22/132=15/x; x = 90.

31. A: The percent increase may be written as (19-12)/12, which equals 7/12, or approximately 58%.

32. C: The first equation may be solved for x. Doing so gives x = 6. Substituting 6 for x, into the expression, 5x + 3, gives 5(6) + 3, or 33.

33. C: The equation, 3002+4002=c2, may be used to solve the problem. Note. After 2 hours, the one plane has ascended 300 miles, while the other plane has traveled 400 miles. Solving the equation for c gives c = 500. Thus, they will be 500 miles apart.

34. A: The area, in feet, may be represented as A = (3W)(3L), or A = 9WL. Since the cost is $0.10 per square foot, the cost will be equal to 9WL x 0.10, or 0.9WL.

35. D: Moving the decimal 9 places to the right involves adding 7 zeros. Doing so gives 8,230,000,000.

36. E: The numbers of visitors for Thursday through Sunday are 345, 1035, 3105, and 9315.

37. E: 0.11 is less than 0.27, 0.25, 0.375, and 0.18.

38. A: The number of boys attending, in 1995, may be written as 0.50(716), which equals 358.

39. A: During 1995, 50% of boys and 50% of girls were in attendance. Thus, 358 boys and 358 girls were in attendance.

40. A: The attendance of boys for the years 1995 through 1998 may be represented as 0.50(716), 0.55(1108), 0.60(1520), and 0.35(2244). The years, 1995 and 1996, show attendance of 358 and 610, while the other two years show attendance of 912 and 786. Thus, the least number of boys attended during 1995 and 1996.
