Question 617649: The available parking area of a parking lot is 900 square meters. A car requires 6 square meters of space and a bus requires 30 square meters of space. The attendant can handle no more than 70 vehicles.
Let c represent the number of cars, and b represent in the number of buses. Write system of inequalities to represent the number of cars and buses that can be parked on the lot.
Draw the graph showing the feasible region.
If the parking fees are $35.00 for cars and $30.00 for buses, how many of each type of vehicle should attendant accept to maximize income? What is the maximum income?
Parking fees for special events are $27.00 for cars and $25.00 for buses. How many of each vehicle should the attendant accept during a special event to maximize income? Whats the maximum income?

Question 617719: There is one homework question I am stuck on and cannot understand what I am doing wrong. We are worknig on graph shifts. The question is,
At a certain vineyard it is found that each grape vine produces about 10 pounds of grapes in a season when about 800 vines are planted per acre. For each additional vine that is planted, the production of each vine decreases by about 1 percent. So the number of pounds of grapes produced per acre is modeled byA(n)=(800+n)(10-0.01n) where n is the number of additional vines planted Find the number of vines that should be planted to maximize grape production.
I have come up with A(n)= -0.01(n+100)^2+8100 and put in the answer of 100, 8100, 800 and many others and nothing is right. I don't understand what I am doing wrong.
