You work for a Carpet company you sell carpet at these prices is 100 ft.² for $67 200 ft.² for $130 400 ft.² for $240 and 800 ft.² for $504 what is the approximate percentage difference of the best and worst carpet deals according to their unit costs ?

i need the options

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
