10. You are buying the hamburgers and chicken for a party. The hamburgers cost $2.75 per pound
and the chicken is $3.50 per pound. If you have $75 to spend, write and solve a linear equation
to find how many pounds of chicken you can afford if you buy 12 pounds of hamburger.

12 pounds of chicken

Step-by-step explanation:

First we have to make 1 equation that represent what the problem says

h = hamburger pounds = 12

c = chicken pounds

h * $2.75 + c * $3.50 = $75

We replace h with 12

12 * $2.75 + c * $3.50 = $75

$33 + c * $3.50 = $75

c * $3.50 = $75 - $33

c = $42 / $3.50

c = 12

step-by-step explanation:

10.50 + taxes which added up to 11.50

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
