Problema Solution
a certain rental service rents video games for 4.99 and movies for 2.99. One day the store rented a total of 35 video games and movies. If teetotal rental income for this day was 144.65, not including tax, what was the total income for movies?
Answer provided by our tutors
let
g = the number of games rented
m = the number of movies rented
the store rented a total of 35 video games and movies
g + m = 35
total rental income for this day was 144.65
4.99g + 2.99m = 144.65
by solving the system of equations
g + m = 35
4.99g + 2.99m = 144.65
we find
g = 20 video games
m = 15 movies
