To calculate the amount Jan will owe at the end of 1 year, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A is the final amount owed
P is the principal amount borrowed ($4,000 in this case)
r is the annual interest rate (4% or 0.04 as a decimal)
n is the number of times the interest is compounded per year (quarterly in this case)
t is the number of years (1 year in this case)
Plugging in the values:
A = 4000(1 + 0.04/4)^(4*1)
A = 4000(1 + 0.01)^4
A = 4000(1.01)^4
Calculating this, we find:
A ≈ $4,161.04
