Jerome is a waiter. he earns $80 each week plus 15% in tips on meals served. this weekend jerome earned $252.50 in all. what was the dollar amount of the meals that jerome served?

$1150

Step-by-step explanation:

Total earnings this week is 252.5 out of which 80 is the fixed amount. So lets find what he earned from tips.

252.5 - 80 = 172.50

Now, let his dollar amount of meals served be "b", so we can say:

15% of b is 172.50

We know "of" means "multiplication" and "is" means equals to. So we translate that word equation to algebraic equation:

15% * b = 172.50

Converting percentage to decimal:

15/100 = 0.15

Now, we write:

0.15b = 172.50

Solving for b:

b = 172.50/0.15

b = 1150

hence,

The dollar amount of the meals that Jerome served was $1150
