Step-by-step explanation:
To calculate how much money Felicity has left after buying the baking supplies, we need to subtract the cost of the supplies from her total earnings. Let's break it down:
1. Felicity earned $25 at the bake sale on Friday.
2. On Saturday, she sold 25 brownies at 50 cents each. This means she earned 25 x 0.50 = $12.50.
3. On Sunday, she bought new baking supplies for $18.
Total earnings = $25 + $12.50 = $37.50
Total expenses = $18
Amount left = Total earnings - Total expenses = $37.50 - $18 = $19.50
Therefore, Felicity had $19.50 left after buying the baking supplies.
