Answer:

Option (A) is correct.

Explanation:

Given that,

Initial price = $10

Initial quantity demanded = 100 units

New price = $8

New quantity demanded = 130 units

By midpoint method,

Average price = (Initial price + New price) ÷ 2

                        = ($10 + $8) ÷ 2

                        = $9

Average quantity demanded:

= (Initial quantity demanded + New quantity demanded) ÷ 2

= ($100 + $30) ÷ 2

= 115 units

Therefore,

Price elasticity of demand:

= (Change in quantity demanded ÷ Average quantity demanded) ÷ (Change in price ÷ Average price)

= (30 ÷ 115) ÷ (2 ÷ 9)

= 0.26 ÷ 0.22

= 1.17 or 1.18

Therefore, the price elasticity of demand between $10 and $8, by the midpoint method, is approximately 1.17.

Ellen Co. has offered their customers a 1% discount off the amount owed if they pay within 15 days of receiving their bill. Hand
bogdanovich [222]

Answer:

Money send to Ellen = $2163.15

Explanation:

Discount offered by the Ellen Co. = 1%

Owed amount = $2185

Since the amount is repaid within 15 days to the offer of a 1% discount will be applicable. So the Handler will send an amount that is 1% less than the actual amount.

Money send to Ellen = 2185 - (1% x 2185)

Money send to Ellen = $2163.15

garri49 [273]

Answer:

In this problem it is necessary to propose and solve the following system of equations:

0.15 X + 0.10 Y + 0.06 Z = 0.09 * 250,000       (1)

X + Y + Z = 250,000                                          (2)

Z = 2 ( X + Y )                                                      (3)

Being the variables

X = $ invested in high-risk stocks

Y = $ invested in medium-risk stocks

Z = $ invested in low-risk stocks

Explanation:

Equation (1) tells us that the sum of the amounts invested in each type of action multiplied by its expected return, is equal to the return that is desired for the entire investment (9% of $ 250,000).

Equation (2) says that the sum of the investments must be equal to the money available to invest.

Equation (3) requires that money invested in low-risk shares (Z) be equal to twice the amount invested in the other two categories.
