A customer deposits $500 in an account that pays 4% annual interest. What is the balance after 3 years if the interest is compou
SIZIF [17.4K]

Answer:

Option D

Step-by-step explanation:

The compounded interes formula states that:

V(t) = P (1 + r/n)^ (nt)

t = years since initial deposit  = 3

n = number of times compounded per year  1

r = annual interest rate (as a decimal)  = 4% / 100 = 0.04

P = initial (principal) investment = $500

Then V(t) = $500 ( 1 + 0.04/1)^3 = 562,43

So the correct answer is option D.

Flura [38]

Answer:

She will earn $85 in 10 hours.

Step-by-step explanation:

If Rachel earned $34 for 4 hours of work, we must divide the amount earned by the number of hours worked in order to find out her hourly rate and then multiply it by 10 to determine how much she would earn if she worked 10 hours.

e = \frac{34}{4}*10\\e=85

She will earn $85 in 10 hours.
