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?
Four of the five figures are worth 4 * 15 = $<T>multiply(4, 15)=60
With one more expensive figure, they are all worth 60 + 20 = $<T>add(60, 20)=80
On all action figures, Jimmy will lose 5 * 5 = $<T>multiply(5, 5)=25 if he sells them cheaper.
So if Jimmy sells the figures he will get 80 - 25 = $<T>subtract(80, 25)=55
