Question

One month kris rented 3 movies and 8 video games for a total of $53. the next month she rented 5 movies and 2 video games for a total of $26. find the rental cost

Answer 1

Make a system of equations and solve for each variable.

3m+8v=53
5m+2v=26

m= movie cost
v= game cost

multiply the bottom equation by 4(combination method)

3m+8v=53
20m+8v=104. Subtract

-17m = -51
m= 3

Plug back into one of the equations

5(3)+2v=26
15+2v=26
2v=11
v=5.5

m=$3
v=$5.5
