movies and
12
video games for a total of
$71
. The next month she rented
5
movies and
3
video games for a total of
$29
. Find the rental cost for each movie and each video game.

Answer 1

Naila,

 

Let m be the rental price of movie and v be rental price of video game

 

2m + 12v = 71

Also 5m + 3v = 29

 

Multiply second eq. by 4

 

20m + 12v = 116

 

Subtract 1 eq from the new eq

 

20m-2m + 12v -12v = 116-71

18m = 45

m = 2.5

 

Movies rent for $2.5.

 

Substitute for m in eq 1

 

2*2.5 + 12v = 71

12v = 66

v = 5.5

 

Video games rent for $5.5
