I need Algebra2 help fast! please?

Question

You are the asst. manager of an appliance store. The manager has asked you to do a cost analysis to figure out what stereo systems the store should order. As asst. manager u need to figure out how much of each model to order to minimize costs. You expect to sell 100 units of Model A and 100 of B. Model A leaces a $40 profit and model B leaves a $60 profit for the store. Total profits must be at least $4800. The wholesale cost of Model A is $250 and b is $400.

1) what does a point in the soloution region represent? How does it compare to a point not in ur soloution region?
Find the maximum and minimum costs
How many of each model should u order to minimize costs?
What is the profit when all items are sold?
The manager decides that the store must order at least 30 model B steros even if it increases the minmum cost.
Now how many of each model should be ordered to minimize costs?
What is the profit when all items are sold?

PLEASEEE help. Ive got about a half hr

Answer 1

OK, not sure if this is totally right, but it's my best guess:)

You need profits greater than or equal to $4,800.00, so you set up this equation:

40A + 60B = 4800

To minimize the costs, you order the max number of cheaper products, so A = 100

4000 + 60B = 4800
-4000 -4000

60B = 800
divide by 60 (both sides)

B = 13.333

So, for minimum cost you would order 100 of product A and 14 of product B.

Your minimum cost would be 100(250) + 14(400) = $30,600.00
This would give you a profit of 100(40) + 14(60) = $4,840.00

Your max cost I assume would be the max you could spend to meet your goal of $4,800.00 profits, so you would buy as many of the most expensive product as you needed to meet your goal and none of product A:

60B = 4800
divide by 60

B = 80

Maximum cost would be 80(400) = $32,000.00
Profit would be 80(60) = $4,800.00

If you need to order at least 30 product B, the equation would be:
B=30
40A + 60(30) = 4800
-1800 -1800

40A = 3000
divide by 40

A = 75

Minimum cost is

A = 75, B = 30
75(250) + 30(400) = $30,750.00

Profit would be

40(75) + 60(30) = $4,800.00
