Yes…. 9p+4 is correct…. GOOD JOB!! :o)
Profit = Revenue – Cost
P = R – C
P = (3y^2 – 2y + 5) – (y^2 + y – 3)
P = 3y^2 – 2y + 5 – y^2 -y +3
P = 3y^2 – y^2 -2y – y + 5 + 3
P = 2y^2 -3y + 8
If your answer for P is positive, that means you made a profit…
BUT…. if your answer for P is NEGATIVE, that means you LOST money and did not make a profit…
