Answer: A. profit of $4500
<u>Step-by-step explanation:</u>
     r(x) = x² + 6x + 10
   - <u>c(x) = x² - 4x + 5</u>
(r - c)(x) =     10x + 5
(r - c)(4) = 10(4) + 5
            =  40 + 5
            = 45
(r - c)(x) represents the profit (in hundreds of dollars) in x months
(r - c)(4) represents the profit (in hundreds of dollars) in 4 months
So, the new store will have a profit of $4500 in 4 months
