Dalco manufacturing estimate that its weakly profit, P, in hundreds of dollars,can be approximated by the formula P= 4x²+8x+7, where x is the number of units produced per week, in thousands.
1)How many units should the company produce per week to earn maximum profit
2)Find the maximum weekly profit.

d(P) = 8x + 8 = 0 for a max/min of P
8x = 8
x = 1
when x = 1
P = 4+ 8+7 = 11
I will leave it up to you to interpret the answer and state the conclusion
