<u>Answer:</u>
The present value of 10,000 if interest is paid at a rate of 6.2% compounded weekly for 8 years is 6097.56
<u>Explanation:</u>
We know that compound interest is given by

Where ,
Where A = final amount (which is given to be = 10000)
P = Principal amount (which is the present amount which we have to find)
r = interest rate = 6.2 = 0.062
n = no. of times interest applied per time period = it is given that the interest is applied weekly, so in one year there are 52 weeks so n = 52
t = time period = 8 years
Substituting the given values, we get

P = 6097.5
We get, P = 6097.56 which is the present value of a sum of money
The unknown number is 1/2 or 0.5.
ex: 4x+6=8
Answer:

Associative property of addition
(a + b) + c = a + (b + c)
Answer: 24%
Step-by-step explanation:
for these problems you can use this equation: 
where x=given quantity, n=total amount, and p is your answer.
for this problem x=18 (regular sodas)
we add the amount of regular and diet sodas to get n=75 (18+57)
when we plug it in we have
which gives us our answer, p, 24%
