George has opened a new store and he is monitoring its success closely. He has found that this store's revenue each month can be modeled by r(x) = 2? + 6x + 10 where x represents the number of
months since the store opens the doors and r(2) is measured in hundreds of dollars
He has also found that his expenses each month can be modeled by c(x) = 22 – 4.3 +5 where x represents the number of months
the store has been open and c(2) is measured in hundreds of dollars.
What does (r - c)(4) mean about George's new store?
