The total cost of a new calculator is $81.05. This price includes a 10% discount followed by a 6.5% sales tax. What was the original price of the calculator not including the tax or the discount?

68.245

Step-by-step explanation:

total cost = $81.05

10% discount is 10/100 * 81.05=8.105

substract 8.105 from 81.05 = 72.945

with a 6.5% sales tax

6.5/100 * 72.954 = 4.7

72.945-4.7 = 68.245 the actual price
