Question

Sarah received $55 for her birthday. She used some of that money to buy 3 shirts priced at m dollars each.

How much money does Sarah have left?

Answer 1

`55 - 3m`

Explanation:

Sarah has $55

Her expenses are 3 shirts priced at $m each.

Total cost of 3 shirts at $m each would be the multiplication of each:

3 * m = 3m

The amount of money Sarah has left would be the total she had MINUS what she spent on 3 shirts. That would be:

Remaining Money = 55 - 3m
