Answer:
$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
