Hi, My names Connie and I'm a student in grade 9. Here's my math problem, if u can figure it out than I I'm very grateful.

Walter is a waiter at the town diner. He earns a daily wage of $100 plus tips that equal to .15 of the total cost of the dinners he serves. What was the total cost of the dinners he served if he earned $170 on Tuesday?


Hi Connie. This is an algebra question. You are trying to find the
total cost of dinners he served, so let's call that C.

Walter earns $100 plus 0.15C, but we know that the total is $170. So we write

100 + 0.15C = 170

Now that this is in equation form, can you solve for C?
