Explanation: Given the range of P, it must be either 5 or 7. Q, similarly, must be either 13 or 17. The smallest value for A is when P = 5 and Q = 13: A = 5(13) = 65. The largest value is when P = 7 and Q = 17: A = 7(17) = 119.
Given the range is between 65 and 119, the correct choice is (C), which sets wider guidelines, between 50 and 150.
