Multiply $75 by 1.1 because it includes the tax and the cake. you should get $82.50.

Answer:

Option D. $82.50

Step-by-step explanation:

The cost of the cake that Melissa bought = $75.00

The sales-tax rate on the cake = 10%

The total amount she paid for the cake = 75 +(10% of 75)

                                                                 = 75 +\((\frac{10}{100}\times 75)\)

                                                                 = 75 + (0.10 × 75)

                                                                 = 75 + 7.5

                                                                  = $82.50

Melissa paid $82.50 for the cake.
