A savings account earns 5% simple interest per year. The principal is $1200. What is the balance after 4 years?

$1458.61

Step-by-step explanation:

Formula: A= P(1+(r/n))nt

A= future amount

P = principal

r = annual interest rate.

n = number of compounding periods per year.

t = number of years.

For your problem,

P= $1200

r = 5% = .05

n = 1

t = 4

A = 1200 * (1+.05)^4

A = 1200 * 1.2155

A = $1458.61

After 4 years, the balance will be $1458.61.

step-by-step explanation:

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 : )
