Answer 1

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

Answer 2

Option D. $82.50

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 +
`((10)/(100)* 75)`

= 75 + (0.10 × 75)

= 75 + 7.5

= $82.50

Melissa paid $82.50 for the cake.
