Step-by-step explanation:

First, multiply the bread cost 2.70 by 2, getting you 5.40.

Next, add 11 for the cost of the caketo 5.40 getting you 16.40

Subtract 16.40 from 20 to get how much money you get for the cookies, getting you 3.60

Divide 3.60 by 3 to find how much money each boy gets, getting you 1.20

Divide 1.20 by .40 to get the number of cookies each boy gets, getting you 3

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
