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.

  • Trig ??? -

    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
