Question

You have a $100 gift card to spend at a store. You buy a portable compact disc player for $45. Compact discs are on sale for $11 each. How many compact discs can you buy with the money remaining on the gift card?

Answer 1

100 - 45 = 55
Since you want to know how much (x) of the discs you can buy with the remaining 55 dollars, set that equal to 11 times x. You get 11x=55. Divide through by 11 and you get 5.
