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
