Answer:
$260
Explanation:
the cash flows associated to this project are:
year 0 = -$150
year 1 = $121
year 2 = -$242
year 3 = $665.50
the discount rate is 10%
using a financial calculator, the project's net present value (NPV) = $260
since the NPV is positive, then this project should be carried out
Answer:
Change in Net worth= $133.62
Explanation:
The two lease options require that the leasee ( the tenant) commit himself to pay a series of equal amount of rent installment at the different time period in the future.
These series of equal periodic cash flows occurring in the future are called annuities.
To have a meaningful comparison, the two annuities should be compared based on their present values. So we compute the present value of the two using the formula below:
Present Value (PV) =( A × (1- (1+r)^(-n))/r
Option 1:Current lease
PV = 500 × 1-(1+0.05)^(12)
= 500 × 8.863251636
= $4,431.62
Option 2: New Offer
This will be done in two steps:
PV of lease in year 3
PV =700 × (1-(1+0.05)^(-9))
= 700 × 7.107821676
=4,975.47
PV of lease in year 0
PV = FV × (1+r)^(-3)
=4,975.47 × 0.8638
=$4,298.00
My net worth would change by the amount of the difference between the two PV of the two annuities:
Difference in PV = $4,431.62-$4,298.00
Change in Net worth= $133.62
Answer:
A. Gretchen is incorrect because there is a binding bilateral contract.
Explanation:
Mainly there are two types of contract i.e unilateral contract and the bilateral contract.
The unilateral contract is the contract when the offer is made to the anyone
while the bilateral contract is the agreement in which the both parties are agreed and bind to perform his/ her obligations.
In the given case, it reflects the bilateral contract as the Haley returns the dog and he requested for the money from the Gretchen
Answer:
n = 100 customers
X = 80 who paid at the pump
A) the sample proportion = p = X / n = 80 / 100 = 0.8
we can definitely state that 80% of the customers paid at the pump.
B) if we want to determine the 95% confidence interval:
z (95%) = 1.96
confidence interval = p +/- z x √{[p(1 - p)] / n}
0.80 +/- 1.96 x √{[0.8(1 - 0.8)] / 100}
0.80 +/- 1.96 x √{(0.8 x 0.2) / 100}
0.80 +/- 1.96 x √{(0.8 x 0.2) / 100}
0.80 +/- 1.96 x 0.4
0.80 +/- 0.0784
confidence interval = (0.7216 ; 0.8784)
C) We can estimate with a 95% confidence that between 72.16% and 87.84% of the customers pay at the pump.
