Answer:
42.3 percent was the tax and tip combined.
Step-by-step explanation:
Given : A $18.00 haircut cost $25.63 after tax and tip.
To find : What percent was the tax and tip combined?
Solution :
Using sales tax formula,
[tex]\text{Sales tax}=\text{Rate}\times \text{Original price}[/tex]
Original price = $18
After tax and tip cost is $25.63
Sales tax = After tax and tip cost - Original cost
Sales tax = $25.63 - $18
Sales tax = $7.63
Substitute the values,
[tex]7.63=\text{Rate}\times 18[/tex]
[tex]\text{Rate}=\frac{7.63}{18}[/tex]
[tex]\text{Rate}=0.423[/tex]
Into percentage,
[tex]\%\text{Rate}=0.423\times 100=42.3\%[/tex]
Therefore, 42.3% was the tax and tip combined.
