The function p(x) = _2(x _ 9)2 + 100 is used to determine the profit on T-shirts sold for x dollars. What would the profit from
Valentin [98]

Answer:

Option (b) is correct.

The profit  from sales if the price of the T-shirts were $15 a pieces is $28.

Step-by-step explanation:

Given : The function p(x)=-2(x-9)^2+100 is used to determine the profit on T-shirts sold for x dollars.

We have to find the profit from sales if the price of the T-shirts were $15 a pieces.

Consider the given profit function  p(x)=-2(x-9)^2+100

For the profit, if the price of a t-shirt is $ 15

Put x = 15, we have,

p(15)=-2(15-9)^2+100

Simplify, we have,

p(15)=-2(6)^2+100=-2\cdot 36+100

Also,  p(15)=-72+100=28

Thus, we get,  The profit  from sales if the price of the T-shirts were $15 a pieces is $28.
