Question 214144
Q = 2m + 3g = 24.30
R = 3m + g = 18.25

Now we subtract the equations to find out one of the variables, put first we need to multiply one of the equations with a number so when they are subtracted it eliminates one of the variables. We will multiply 3 to R equation;

(3)3m+g = 18.25
9m+3g = 54.75

Now we can subtract;

2m+3g=24.3
-(9m+3g=54.75)
---------------
-7m=-30.45
m=4.35

So we know the movies are $4.35
Lets plug that into the either equation to find g;

2(4.35)+3g=24.30
8.7+3g=24.30
3g=15.6
g=5.2

Games = $5.20

S = 4.35+2(5.2)
S = 4.35 + 10.4
S = 14.75
