A sporting goods store sold 64 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?  Choose the correct choice from the following options: A) 24 B) 8 C) 12 D) 4 E) 2
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 = 64   3x + 4y = 200   x = 64 - y   3(64-y) + 4y = 200   192 - 3y + 4y = 200   y = 8   Answer: 8
