Answer:
annual withdrawals is $1,393.87
Explanation:
given data
Amount Deposited = $5,000
Annual Interest Rate = 7.2%
First withdrawal = 2020
last withdrawal = 2025
solution
we consider equal sized annual withdrawals = x
so we can say that Amount Deposited amount will be as
$5,000 =
..........1
we take common here
so
$5,000 =
solve it we get
x = $1,393.87
so that annual withdrawals is $1,393.87
Answer:
B) 0.7; inelastic
Explanation:
The computation of the absolute value of the price elasticity of demand is shown below:
Elasticity is
= [(Sales - prior sales) ÷ ( Sales + prior sales) ÷ 2] ÷ [(price - dropped price) ÷ (price - dropped price) ÷ 2
= [(1,040,000 - 890,000) ÷ (1,040,000 + 890,000) ÷ 2] ÷ [(25,000 - 20,000) ÷ (25,000 + 20,000) ÷ 2]
= (150,000 ÷ 965,000) ÷ (5,000 ÷ 22,500)
= 0.15 ÷ 0.22
= 0.7
It is less than one so the demand is inelastic
Answer:
21
Explanation:
Given that:
The utility function U(x, y) = 
The budget line income is:
105=4x +3y
The equation MRTS is:

where;


and:


∴
Using the equation MRTS:



4x = 12y
x = 12y/4
x = 3y
Replacing the value of x into the budget line income, we have:
105 = 4x + 3y
105 = 4(3y) + 3y
105 = 12y + 3y
105 = 15y
y = 105/15
y = 7
Then, from x = 3y
x = 3(7)
x = 21
Thus, she will consume 21 gapefruits
