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

uppose that grade point averages of undergraduate students at one university have a bell-shaped distribution with a mean of 2.5
Marizza181 [45]

Answer:

P(x \le 3.24) = 0.97725

Step-by-step explanation:

Given

\bar x = 2.5

\sigma = 0.37

Required

Percentage that is not more than 3.24

The above implies that:

x = 3.24

Calculate z score

z = \frac{x - \bar x}{\sigma}

z = \frac{3.24 - 2.5}{0.37}

z = \frac{0.74}{0.37}

z = 2

So, the probability is represented s:

P(x \le 3.24) = P(z \le 2)

From z probability

P(z \le 2) = 0.97725

Hence:

P(x \le 3.24) = 0.97725
