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
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.
