Answer:

The total amount that Melissa paid for the cake is $82.5

Step-by-step explanation:

we know that

The total amount that Melissa paid for the cake is equal to the cost of the cake plus the sales tax

we have that

the cost is equal to $75

Find the sales tax

The sales tax is 10%, therefore find the 10% of the cost of the cake

10%=10/100=0.10

so

(0.10)*$75=$7.5

Adds the cost and the sales tax

$75+$7.5=$82.5
