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 .

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
