Nathan put $200 in a savings account for two years. The interest rate is 5% and will be compounded annually. How much money will he have at the end of the two years?

Nathan will have $220.5 at the end of the two years.

Step-by-step explanation:

We are given the following in the question:

P = $200

r = 5% = 0.05

t = 2 years

The compound interest is given by:

where A is the amount, p is the principal, r is the interest rate, t is the time in years and n is the nature of compound interest.

Putting values, we get,

For n = 1

Thus, Nathan will have $220.5 at the end of the two years.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
