Question

John owns a hotdog stand. He has found that his profit is represented by the equation P(x)=-x+ 10x +32, where x is the number of hotdogs. What is the most he can earn? A. $16 OB. $10 OC. $57 OD. $32

Answer 1

Step-by-step explanation: R=P.Q =
`x.(-x+10x+32) = 9x^(2) + 32x`

R(x) = 0 (x>0) ⇒ ⇒
`9x^(2) +32x=0`⇒
`\left \{ {{x=0} \atop {x=-(32)/(9) }} \right.`

Change x=0 into P(x) ⇒ (D) 32 dollars
