Answer:
$82.58
Explanation:
The total cost of the meal = cost of meal + tip amount - discount amount
We then need to find the tip amount and the discount amount using the given cost of the meal, tip percent, and discount percent.
the tip amount applies to the cost of the meal before the discount. Since the cost of the meal before the discount is $78.65 and the tip percent is 20% then the amount of the tip is: 20% of $78.65= 0.20 x $78.65 = $15.73
Since the cost of the meal before the discount is $78.65 and the discount percentage is 15%, then the amount of the discount is: 15% of $78.65 = 0.15 x $78.65 = $11.80
(Remember that the discount amount needs to be rounded to two decimal places since dollar amounts should be rounded to the nearest cent.)
The total cost is then:
$82.58
Hope this helps!
