Answer:
A sample of 1068 is needed.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
The margin of error is:
95% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
At 95% confidence, how large a sample should be taken to obtain a margin of error of 0.03 for the estimation of a population proportion?
We need a sample of n.
n is found when M = 0.03.
We have no prior estimate of , so we use the worst case scenario, which is 
Then
Rounding up
A sample of 1068 is needed.

Answer:
120 - (W*7)= A
Step-by-step explanation:
Let's say after 3 weeks. $120 is what he owes her in the beginning. He pays her $7/week.
After 3 weeks, he owes her 120 - (W*7)= A.
W=3, since we are 3 weeks along. So, after 3 weeks he still owes her
120 - (3*7)= A >>> 120 - 21= A >>> 99= A.
