The question is incomplete:

Reyna runs a textile company that manufactures T-shirts. The profit, p, made by the company is modeled by the function p = s^2+9s-142, where s is the number of T-shirts sold. How many T-shirts should be sold to earn a profit of more than $2,000?

s>42

Reyna needs to sell more than 42 T-shirts.

Step-by-step explanation:

Given that you have to find the amount of T-shirts that should be sold to earn a profit of more than $2,000, you have to find the amount required to earn $2,000 by replacing p with 2,000 and solving for s:

s^2+9s-142=2000

s^2+9s-2142=0

(s+)^2-2142-()^2=0

(s+)^2=2142+()^2

(s+)^2=2142+

(s+)^2=

s+=

s=

s=

s=

s=42

According to this, Reyna needs to sell more than 42 T-shirts to earn a profit of more than $2,000.
