The Jayden family eats at a restaurant that is having a 15% discount promotion. Their meal costs $78.72 before the discount, and they leave a 20% tip. If the tip applies to the cost of the meal before the discount, what is the total cost of the meal? Round your intermediate calculations and answer to the nearest cent.

The total cost of the meal is $

Answers

Answer: $82.65

Explanation:
78.72 • 0.15 = 11.808; $11.81 (amount taken off regular price)

78.72 • 0.20 = 15.744; $15.74 (amount you will leave as tip)

$78.72 - $11.81 = $66.91;

$66.91 + $15.74 = $82.65

Answer: 21

Step-by-step explanation: We can use the method: Keep, Change, Flip.

1. Keep 7.

If you want 7 to become a fraction, you can do it like this: [tex]\frac{7}{1}[/tex]

2. Change division to multiplication.

It's very simple. Just change the sign.

3. Flip [tex]\frac{1}{3}[/tex].

It's like converting it into a improper fraction. [tex]\frac{1}{3}[/tex] is now [tex]\frac{3}{1}[/tex].

Now we can solve!

[tex]\frac{7\times3}{1\times1} =21/1[/tex]

Therefore, your answer is 21/1 or just 21.
