Answer:
6.6% = tax rate
Step-by-step explanation:
The first step is to find out how much was paid in tax
24.91 - 23.37 =1.54
The tax is 1.54
The tax is the original price * tax rate
1.54 = 23.37 * tax rate
Divide each side by 23.37
1.54/23.37 = tax rate
.065896448= tax rate
Changing to percent form
6.6% = tax rate
