You will have 2 equations for this problem
For theater one, f(x), you will have a base cost of 25 and a slope of 7, being f(x)=7x+25
For theater two, g(x), you dont have a base, but you have a slope of 12, being g(x)=12x

deepolisnoob · Answer

you want both theaters to have an equal price, so f(x)=g(x), so 7x+25=12x. You get your x values on one side, making your equation 25=5x. divide both sides by 5, and you are left with x=5

i think the amount of movies should be 5 because the formula 7x+25=12x.  You combine like terms, and the final answer is 5 :)
