A sporting goods store sold 60 Frisbees in one week, some for $3 and the rest for $4 each. If receipts from Frisbee sales for the week totaled $200, what is the fewest number of $4 Frisbees that could have been sold? Select
A) 24  B) 12  C) 20  D) 4  E) 2
The wording of the question is slightly misleading. When a question asks what is thefewestthatcouldhave been sold, it is suggesting that there could be many different quantities sold.   In this question however, because we are told that exactly 64 Frisbees have been sold and revenue was exactly $204, there is only one possible solution for the number of $3 and $4 Frisbees sold.   To solve, we have 2 equations and 2 unknowns   Let x = number of $3 Frisbees sold   Let y = number of $4 Frisbees sold   x + y = 60   3x + 4y = 200   x = 60 - y   3(60-y) + 4y = 200   180 - 3y + 4y = 200   y = 20   Answer: 20
