Patrick earned $330 mowing lawns during the summer months. He bought 4 boxes of candies worth $16 each from his lawn-mowing money. How much money was left after he bought the boxes of candies?

Answer 1

Welcome to QuestionCove.
Simplest way to do this is multiplying 16 by 4 (16 x 4), or adding 16, 4 times (16 + 16 + 16 + 16) which will come out to 64.
With that, you subtract 330 from 64. (330 - 64)
When done subtracting that, the final number is what your answer will be.
