Thanks a lot, will do that now

I found P= 87X - 700 - X^2 after my calculations, I just need a little help on where to go from there??

P = 87x - 700 -x^2 1. Draw a graph of P against x and estimate the maximum value of P and also calculate the coordinates of the stationary point and verify if it is maximum. I am not very good at graph drawing or stationary points... any help people?

I am not very good with graph drawing, so finding the linear programming problem graphically and finding the feasible region, optimal point would be difficult for me. Are there any easy way of finding these after obtaining the constraints??

How do I do the customer demand constraint?

P= 15x + 5y subject to 4x + 5y > 200 1x + 3y > 90 x > 0 y > 0 That's my constraints

Yea I have found the profit and the constraints, just don't know how to draw the graph showing the optimal point, iso-profit and optimal profit.

A furniture manufacturer makes chairs and sofas. Each chair can be sold for a profit of £15 and each sofa for a profit of £5. It takes 4 hours to make the chair and 5 hours to make the sofa. The manufacturer has enough workers to provide 200 hours per week producing the furniture. Customer...

info given were: 2 cylinders= 125N.m 4 '' =80N.m 6 '' = 65N.m

I was told to choose a car, a petrol car, and using the engine size of the car(1798cc), work out the power of the starter motor the car would require. The cars specs are: 1798cc, 4 cylinders.

How do I calculate the estimated power of a motor needed for a ford focus, engine size:1788cc, 4 cylinders??
