Michelle has starting balance on a gift card for $300. She buys several dresses at $40 a piece. After her purchase she has $140 left on her gift card. How many dresses did she buy?

4 dresses

Step-by-step explanation:

If she starts with $300 and ends up with $140, that means that she spent $160. So, since each dress costs $40, you divided $160 by $40, which equals 4. So Michelle bought 4 dresses.

(hope this helps!)
