Answer:
$500
Step-by-step explanation:
Wages = $30
Tips = 15% of on customers food bill
if the waiter earns a total of $105, what is the customer's food bill?
15 % of customers food bill = Total earned - wages
= $105 - $30
= $75
15 % of customers food bill = 75
Let x = customer's food bill
15% of x = $75
0.15x = 75
x = 75 / 0.15
= $500
x = $500
Therefore, customer's food bill is $500
