rental cost for each movie and each video game,

Answer 1

movie costs $1.25

Video game costs $5.50

Explanation:

4x + 8y = 49 , 2x +3y = 19. By solving for x first, we get x=5/4. After substituting x into the equation, we get 4(5/4) + 8y =49 , 2(5/4)+3y=19 and then we solve for y. and we get y=11/2. check our answer, and it is true.
