Luke puts $200 into his account to use for school expenses. The account earns 2% interest, compounded annually. How much will be in the account after 7 years?

$230 will be in the account after 7 years.

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = 200

r = 2% = 2/100 = 0.02

n = 1 because it is compounded once in a year.

t = 7 years

Therefore,.

A = 200(1+0.02/1)^1 × 7

A = 200(1.02)^7

A = $230

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
