Question 40810
Walter ia a waiter. he earns a daily wage of $50, plus tips that are equal to 15% of the total dinners he serves. what was the total cost of the dinners he served if he earned $170 on tuesday?

Let total cost of the dinners be "x"

EQUATION:
 The waiter's earnings will be 50+0.15x = 170
0.15x=120
15x=12000
x=$800 (total cost of the dinners)
Cheers,
Stan H.
