If the edwards drive 225 miles, which company would be a better deal? if the edwards only have to spend, which company would be a better deal?

i can give you the exact answer to your question, but what are the equations for the companies and  how much do the edwards have to spend? if not, here's how to do it:

y= m(225)+b for each company. i used slope-intercept form assuming that's what form the equations are written in. it's basically saying x=225 in part a (look for the lowest y) and in part b y≥m(225)+b (look for which company's equation makes the statement true)

(ps i'm checking every few minutes if you want to comment and get the exact answer)

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
