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

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 9 is an expression.

We have,

From the table,

The pattern that describes the table.

Let the pattern be z = mw + c

Now,

(3, 27) and (5, 45)

m = (45 - 27) / (5 - 3) = 18/2 = 9

Now,

(3, 27) = (w, z)

27 = 9 x 3 + c

27 - 27 = c

c = 0

Now,

The pattern for the table.

z = 9w

Thus,

The patter for the table is z = 9w.

A dinner cost $28.50 which included a 15% tip. How much was the tip?

Answers

Answer: $4.28

Tip: $4.275 = $4.28

Step-by-step explanation:

Use the formula: Tip = Tip% x Bill Total

In this case, the tip is 15% and the total bill is $28.50.

15% = 0.15

28.50 x 0.15 = 4.275

Round 4.275 to the hundredths, which equals 4.27

Answer: Tip: $4.275 = $4.28

Step-by-step explanation:

Use the formula: Tip = Tip% x Bill Total

In this case, the tip is 15% and the total bill is $28.50.

15% = 0.15

28.50 x 0.15 = 4.275

Round 4.275 to the hundredths, which equals 4.27

Answer:

$4.28

Step-by-step explanation:

15%= 0.15

0.15*28.50= 4.275

Simplified: $4.28
