The store has y shirts. It's almost alarm for $16 each, and the last dozen were sold on sale for $14 each. If it's all the shirts for $616, find the number of shirts sold.

The answer is 40 shirts.

Explanation

Equation: y = ((616 - (14*12)) / 16) + 12

First, multiply the 12*14 because we know that 12 shirts were $14. You'll get $168. Next, subtract that from 616, the total number of dollars, to get the 12 shirts out of the way. Your answer will be $448. Then, divide by 16 because that's the remaining money that was spent on the $16 shirts. You'll get 28 shirts. However, we can't forget about the dozen $14 shirts, so add 12 to your answer and you get 40 shirts.
