Answer:
Step-by-step explanation:
n is the number of times the interest compounds per year. If the interest in this problem only compounds once per year ("annually"), then n = 1 and you'd be just as well off to use the formula:
When n = 1, r/n is just r. But I'll show you using the formula they want you to use; it's the same anyways.
For us, P = 500, r = .015, n = 1. Filling that into the formula:
which simplifies down to
and
(see what I meant about not having to use the formula with "n" in it if n 1?)
That formula is the answer to part a. For part b, we are to find how long it takes for the account to reach $800. $800 goes in for A:
Begin by dividing both sides by 500 to get:
The only way to bring that t down from its current exponential position is to take the natural log of both sides. I will do that and at the same time apply the power rule for logs which says the exponent will come down out in front of the log:
Divide both sides by ln(1.015):
Do this on your calculator to find that
t = 31.5 years

its 144
