Question

a large hardware store’s monthly profit from the sale of pvc pipe can be described by the equation ( p(x) = 6.10x - 9760 ) dollars, where ( x ) is the number of feet of pvc pipe sold. what level of monthly sales is necessary to avoid a loss?
how much pvc pipe must be sold?
(square) ft

Explanation:

Step1: Set profit to 0 (break-even)

$P(x) = 0$

Step2: Substitute profit equation

$6.10x - 9760 = 0$

Step3: Isolate the term with x

$6.10x = 9760$

Step4: Solve for x

$x = \frac{9760}{6.10}$

Answer:

1600 ft
