Answer:
$15 per backpack
Explanation:
The average variable cost per of producing a backpack by using the high low method is shown below:
Variable cost per backpack = (High total cost - low total cost) ÷ (High backpack produced - low backpack produced )
= ($110,000- $87,500) ÷ (4,000 backpack produced - 2,500 backpack produced )
= $22,500 ÷ 1,500 backpack produced
= $15 per backpack
Explanation:
i=interest rate
X=current rate
2X = double current rate
n = number of years
Calculate time it takes to double at 3%:
2X = X(1+i)^n
simplify by cancelling out X
(1+i)^n = 2
substitute i = 3%
(1.03)^n =2
take log
n*log(1.03) = log(2)
n = log(2)/log(1.03) = 0.6931/0.02956 = 23.45 years
Similarly, for growth rate of 7%,
n = log(2)/log(1.07) = 0.6931 / 0.06766 = 10.24 years
So the difference is 23.45-10.24 = 13.21 years (to the hundredth) sooner
The standard deviation of sample equals: 11
Explanation:
Given:
variance of sample (
) = 121
no, of observations made = 441
standard deviation = ?
By using the formula:
Standard deviation (S) = 
= 
= 
= 11
Hence the standard deviation is equal to 11.

Answer: some consumers are willing to pay more than the equilibrium price.
Explanation:
Consumer Surplus is simply the difference between the price that is paid by a consumer and the price that the consumer was willing to pay in the first place.
In an unregulated, competitive market consumer surplus exists because some
consumers are willing to pay more than the equilibrium price.
