Question

A customer gave her hair dresser a 20% tip, which amounted to $7. What was the price before the tip?

Answer 1

Answer:

The price before tip was 35

Step-by-step explanation:

Let x = original amount

x * 20% = 7

Change to decimal form

x * .20 = 7

Divide each side by .20

x*.20/.20 = 7/.20

x =35
