Answer

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

= 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 .
