when Lisa and Tom had their first child. they put $7,500 into a savings account, that earns 6% compound interest. if Lisa and Tom did not add or remove anything ,from the savings account. how much interest will they have earned after 4 years.

Answer:
$1,968.6
Step-by-step explanation:
Compound Interest = [P * (1 + i)ⁿ] - P
P = principal = $7,500
i = annual interest rate = 6%
n = number of periods = 4 years
Compound Interest = [$7,500 * (1 + 0.06)⁴] - $7,500
Compound Interest = [$7,500 * (1.06)⁴] - $7,500
Compound Interest = [$7,500 * (1.06)⁴] - $7,500
Compound Interest = [$7,500 * 1.26247696] - $7,500
Compound Interest = $9,468.5772 - $7,500
Compound Interest = $1,968.5772
