Jimmy has a collection of 5 action figures. Each figure is worth $15, except for one which is worth $20. He decided to sell his collection. To do it fast he decided to sell each of them for $5 less than their value. How much will Jimmy earn if he sells all the figures?
Let's be accurate as possible and think first.
55
Four of the five figures are worth 4 * 15 = $60.

With one more expensive figure, they are all worth 60 + 20 = $80.

On all action figures, Jimmy will lose 5 * 5 = $25 if he sells them cheaper.

So if Jimmy sells the figures he will get 80 - 25 = $55.

.

The answer: 55
