Mrs. margul paid $125 to have her hair colored and cut if she tips her hairdresser 15% what is her total bill

143.75

Step-by-step explanation:

The tip is the cost times the tip rate

tip = cost * rate

The cost is 125  and the rate is 15%

tip = 125 * 15%

Change this to decimal form

tip = 125 *.15

    = 18.75

The total bill is the cost plus the tip

total bill = cost + tip

             = 125 + 18.75

             = 143.75
