Question

Emily takes her friend Darren out to eat for his birthday. She pays a total of $45, which includes a 20% tip. There is no tax. Find the cost of the meals before the tip

Answer 1

Answer: $37.50

Explanation:

Let c= cost before the tip

*Turn 20% into a decimal

c+ 0.20c=45

1.20c=45

45/1.20=37.50

That is the cost before the meal.

Answer 2

Find the cost of the meals before the tip.

To prove

As given

Emily takes her friend Darren out to eat for his birthday.

She pays a total of $45, which includes a 20% tip.

20% is written in the decimal form

`= (20)/(100)`

= 0.20

Cost of the tip = 0.20 × 45

= $ 9

Thus

Cost of the meals before the tip = Cost of the meal with tip - tip cost

= $45 - $9

= $ 36

Therefore the cost of the meals before the tip is $36 .
