1x + 1y = 100....multiply by -3/8
3/8x + 7/8y = 2000

no need to multiply the other equation by anything....the x's will cancel because one will be -3/8x and one will be 3/8x

A company finds that if they price their product at $ 35, they can sell 225 items of it. For every dollar increase in the price,
Basile [38]

Answer:

Maximum revenue = $8000

The price that will guarantee the maximum revenue is $40

Step-by-step explanation:

Given that:

Price of product = $35

Total sale of items = 225

For every dollar increase in the price, the number of items sold will decrease by 5.

The total cost of item sold = 225 ×35

The total cost of item sold = 7875

If c should be the dollar unit in price increment;

Therefore; the cost function is : [35+c(1)][225-5(c)]

For maximum revenue;

\dfrac{d}{dc}(cost \ function) =0

\dfrac{d}{dc}[[35+c(1)][225-5(c)]]=0

0+225-35× 5 -10c = 0

225 - 175  =10c

50 = 10c

c = 50/10

c = 5

Maximum revenue = [35+c(1)][225-5(c)]

Maximum revenue = [35+5(1)][225-5(5)]

Maximum revenue = (35 + 5)(225-25)

Maximum revenue = (40 )(200)

Maximum revenue = $8000

The price that will guarantee the maximum revenue is :

=(35 +c)

= 35 + 5

= $40
