Question

Shirley went to the beauty shop to get her hair done, the cost was $75. She gave the hairdresser a 10% tip. The salon adds a sales tax of 8.25%. What was her tax on the bill? * What is her total cost? How much did she tip the hairdresser?

Answer 1

Shirley paid $75 in a hairdressing. The tax was 8.25% of the cost, so:

$\text{tax}=75\cdot\frac{8.25}{100}=\frac{618.75}{100}=6.1875$

The tips for the hairdresser was 10% of the cost, same as before:

$\text{tip}=75\cdot\frac{10}{100}=\frac{750}{100}=7.5$

The total cost was the sum of the cost, the tax and the tip:

$\text{total cost=cost+tax+tip=75 + 6.1875 + 7.5= 88.6875}$

The total cost is $88.6875
