Answer:
$74.8
Step-by-step explanation:
step 1: apply the discount to the price
12% = .12
$79.97 X .12 = $9.5964
$79.97 - $9.5964 = $70.3736
step 2: apply tax
$70.3736 X .0625 = $4.39835
$70.3736 + $4.39835 = $74.77195
step3: round
$74.8
Answer:
6546 students would need to be sampled.
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 z-score that has a p-value of
.
The margin of error is:

The dean randomly selects 200 students and finds that 118 of them are receiving financial aid.
This means that 
90% confidence level
So
, z is the value of Z that has a p-value of
, so
.
If the dean wanted to estimate the proportion of all students receiving financial aid to within 1% with 90% reliability, how many students would need to be sampled?
n students would need to be sampled, and n is found when M = 0.01. So






Rounding up:
6546 students would need to be sampled.
5x+x=42
6x=42
x=7
So the numbers are 7 and 35 (5*7)
