1.
In line with the test each person who came into interaction
with the infected person will become infected also. With this information, the
calculation would be: 9 people each day for 7days would be equivalent to 9 x 7
which equals 63 people.
2.
Here were 7 other people in the experiment if patient
zero is left out. If each person intermingled with 6 different people every day
in 7 days then the calculation would be: 7 people infected x 6 new people = 42
infected people each day
42 new people every day x 7 days = 294
infected persons.
Answer:
The monthly payment will be $531.12
Step-by-step explanation:
Consider the provided information.
After paying $5,000 down payment you need to pay:
$29,000-$5,000=$24,000
APR is 2.99% or APR = 0.299%
Therefore, 
n = 48
We can calculate the monthly payment by using the formula:

Where P is the monthly payment, PV is the present value, r is the rate per period and n is the number of period.
Substitute the respective values in the above formula we get,



Hence, the monthly payment will be $531.12
