Answer:
lower range 33.822 years
upper range 38.178 years
Explanation:
step 1:
48 -1 = 47
step 2:
(1 - 95%) / 2 = 0.025
step 3:
we look at the T distribution table for degrees of freedom (df) = 47, and α = 0.025; = 2.0117
step 4:
divide sample standard deviation by square root of sample size
7.5 years / √48 = 7.5 / 6.9282 = 1.0825
step 5:
multiply results from step 3 and 4
2.0117 x 1.0825 = 2.178
step 6:
for the lower range, subtract step 5 from sample mean
36 - 2.178 = 33.822
step 7: for the upper range, add step 5 with sample mean
36 + 2.178 = 38.178
Explanation:
Income Elasticity of Demand(IED)= Percentage change in quantity demanded/ Percentage change in income
-Percentage change in Q:
%Change in quantity demanded= (q2-q1/q1) = (10-8)/8= 0.25
-Percentage change in Income:
%Change in income= (i2-i1/i1) = (4,500-4,000)/4,000= 0.125
IED= 0.25/0.125= 2
This indicates that the Shaffers are very sensitive to changes in income when it comes to eating out. Which means that changes in income will change significantly the number of times they eat out.
2. Restaurant meals are normal goods, in this case, because when income rises, they ate more in restaurants, then the units consumed for this good increase too.
Answer:
The amount that should be deposited today is $33254.58
Explanation:
The deposit should be such that the future value of the deposit made today and at the end of year 2 should be equal to $50000 after 5 years. Let the deposit made today be x. The equation for the future value will be,
50000 = x * (1+0.045)^5 + 7500 * (1+0.045)^3
50000 = x * (1.045)^5 + 8558.745938
50000 - 8558.745938 = x * (1.045)^5
41441.25406 / (1.045)^5 = x
x = $33254.57769 rounded off to $33254.58
Answer:
If sold without Modification, Armstrong Corporation will incur a loss of $12,500.
If the Corporation modifies the Stock and then Sell it, its loss will be $9,200.
Explanation:
<u>Workings</u>
Without Modification:
Selling Price = 7,300
Less: Cost of Inventory = 19,800
Loss = $12,500.
Modification:
Selling Price = 20,900
Less: Cost of Inventory = 19,800
Modification Cost = 10,300
Loss = $9,200.
