### SAT test Sample Questions 71-90 Answers & Explanations

**71. A: The original price of the desk may be found by solving the equation, 0.25x = 45. Thus, x = 180. However, this is the original price of the desk. Since he saves $45, he pays $45 less, or $135.**

**72. C: The following equation may be used to find the value of the car: 1,100 = 0.089x. Solving for x gives x ≈ 12,359.55. Thus, the value of the car is $12,359.55.**

**73. A: The formula, I = Prt, represents the amount of interest earned, for a particular principal, interest rate, and amount of time. Substituting 210 for I, 3000 for P and 0.07 for r gives: 210 = 3000(0.07)t. Solving for t gives t = 1. Thus, he will earn $210 in interest, after 1 year.**

**74. B: The percent increase may be modeled by the expression, (14,000-12,000)/12,000, which equals 16.7%.**

**75. E: The equation, 0.35x = 70, may be used to solve the problem. Dividing both sides of the equation by 0.35 gives x = 200.**

**76. B: The problem may be modeled as x = 0.05(2000). Thus, 100 is 5% of 2000.**

**77. C: The problem may be modeled as 90x = 27. Dividing both sides of the equation by 90 gives x = 0.3 or 30%.**

**78. D: The percent increase may be modeled by the expression, 0.75/15.50, which is approximately 0.048, or 4.8%.**

**79. A: The first part of the problem may be modeled with the equation, 45 = 1.2x. Solving for x gives x = 37.5. 80% of 37.5 may be written as 0.80(37.5), which equals 30.**

**180. C: The formula, I = Prt, represents the amount of interest earned, for a particular principal, interest rate, and amount 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. Thus, she will have to wait 4 years to earn $600 in interest.**

**81. C: The second part of the problem may be modeled with the equation, 12 = 0.15x. Solving for x gives x = 80. Thus, the number is 80. 35% of 80 may be written as 0.35(80), which equals 28.**

**82. C: The sale price of the computer is 80% of the regular price. Thus, the following equation may be used to solve the problem: 1600 = 0.80x. Solving for x gives x = 2000. Thus, the regular price of the computer is $2000.**

**83. B: The following equation may be used to solve the problem: 0.25=(39,000-x)/x. Multiplying both sides of the equation by x gives 0.25x = 39,000 - x. Adding x to both sides of the equation gives 1.25x = 39,000, where x = 31,200. Thus, the cost of the SUV to the dealer was $31,200.**

**84. E: The problem may be modeled by the expression, 49,000 - (0.20(49,000)), which equals 39,200. Thus, he had to sell the car for $39,200.**

**85. B: The attendance of employees and spouses may be modeled as 1/2+1/3, or 5/6. Thus, 1/6 of those, in attendance, who are not employees or spouses, is approximately 16.7%.**

**86. B: The first part of the problem may be modeled with the equation, 6 = 0.24x. Solving for x gives x = 25. Thus, the number is 25. 40% of this number may be written as 0.40(25), which equals 10.**

**87. A: The problem may be modeled as 0.25(400), which equals 100.**

**88. B: The problem may be modeled as 0.22(900), which equals 198.**

**89. D: The percentage may be obtained by multiplying 0.45 by 100. Doing so gives 45%.**

**90. C: The percentage may be obtained by multiplying 1.25 by 100. Doing so gives 125%.**
