Answer:
The lease payment will be for $ 113,751.173 during 5 years beginning at the moment the lease is signed
Explanation:
First, we discount the payment at the end of the lease
Maturity $150,000
time 5 years
rate 0.06
PV 112,088.7259
Now we subtract form the 620,000 to know the amount to be perceived form the lease payment:
620,000 - 112,089 = 507.911
Now we solve the PMT which makes the annuity-due of 5 payment at the beginning of the period:
PV $507,911.0000
time 5
rate 0.06
[tex ]507,911 \div \frac{1-(1+0.06)^{-5} }{0.06}(+0.06) = C\\[/tex]
C $ 113,751.173
The closest to the minimum number of consumers needed to obtain the estimate with the desired precision is (b) 271
Explanation:
When the prior estimate of population proportion is not given , then the formula to find the sample size is given by :-
where E = Margin of error.
z* = Critical z-value.
As per given , we have
E = 5%=0.05
Confidence level = 90%
The critical value of z at 90% is 1.645 (By z-table)
Put all values in the formula , we get
n=0.25(1.645/0.05)²
n=0.25(32.9)²
n=270.6025≈271
Thus, the minimum sample size needed = 271
Hence , the correct answer is 271 .
