Hey You!

Let's solve this step-by-step:

9.99 * 20% = 1.998

9.99 - 1.998 = 7.992

7.992 * 6.75% = 0.53946

7.992 + 0.53946 = 8.53746

The total cost of his order is $8.53

Answer:

$8.53

Step-by-step explanation:

$9.99 x .80 - the .80 is 80% off the original price, hence 20% off. Then multiply by 1.0675 for the total price plus 6.75% sales tax.
