Step-by-step explanation:
Tax equals the original amount times the tax rate
We can find the tax by taking the amount he paid minus the original amount
tax = 156.6 - 145
tax = 11.6
tax = original amount * tax rate
11.6 = 145 * tax rate
Divide each side by 145
11.6/145 = 145/145 * tax rate
.08 = tax rate
To change this to percent, multiply by 100%
.08*100% = 8%
