im bad at math pls help me out

Question

At an Italian restaurant, you order a salad for $2.50 and spaghetti for $8.25. Sales tax is 7.5%. What is the total of your bill including sales tax?

Answer 1

2.5 + 8.25 = 10.75 = total cost before the tax

= 10.75(1.075) = total cost after tax

= 11.55625

= $11.56

= total cost after taxes, rounded to nearest cent

tax rate = 7.5% = 0.075

tax on the meal cost .075 x 10.75 = .80625 = 81 cents

meal plus tax = 10.75 + .81 = 11.56 = $11.56
