Answer
Sales tax: 6 dollars 41 cents
Total cost: 91 dollars 91 cents
Work Step by Step
To find the sales tax, multiply the purchase price by the tax rate of 7.5%
85.50 $\times$ 0.075 = 6.4125, which, rounded to the hundredth decimal place is 6.41.
Then, add the sales tax with the purchase price to get the total cost.
6.41 + 85.50 = 91.91
So the total price is 91 dollars and 91 cents.
