Answer:
The best answer should be $6.80 after discounts and taxes. (Not Rounded) | See below for rounded variable
Explanation:
$6.99 x .10 = .699 (69 cents) (70 cents rounded) [DISCOUNT]
$6.99 - .69 = $6.30 [AFTER DISCOUNT]
$6.30 x .08 = .504 (50 cents) [SALES TAX]
$6.30 + .50 = $6.80 ( Not rounded )[TOTAL AFTER DISCOUNT/TAX]
$6.79 if you are suppose to round the .699 to .70
