D is the correct equation for this problem.
He didn't distribute 1/3 to x and 15 before solving
The average is 30 because 36+26+30+28=120 divided by 4 = 30
The tax is 6.5% OF the listed price. "OF" in math means multiply.
First convert the percentage to a decimal
6.5% = .065
Then multiply .065*813.95 = 52.90675. This is the tax.
Simply add the tax onto the cost
813.95 + 52.90675 = $866.86 (rounded)
