mr. and mrs. dobrosky are eating at friendly's. their bill is $24.79 and they are leaving a 15% tip. how much did they spend on dinner and the tip?

Tip: $3.70

Total: $28.49

Step-by-step explanation:

1. Finding the tip:

a. tip = total cost * rate of tip

or you could do it as a proportion, which would be
