Answer:

a) $2380
b) $2832.2

Explanation:

Compound Interest Formula:


A=P(1+(r)/(n) )^n^t

Compounding interest is when it increases exponentially every year. When it increases 19% per year, you multiply by 19% the new amount instead being based off the original value. In this case, after a year, 119% of 2000 would be 2380. Then, you would multiply 2380 by 119% to get the new amount (2832.2), instead of adding 19% of 2000 again (if it were simple interest you would just add 380 again instead of compounding).

A is the final amount after compounding.

P is the principle, or the amount you start with.

R is the interest rate.

t is the number of time periods (in this case 1/2 years).

n is the number of times interest is applied per time period (t) (it's still 1/2 because the interest is applied once per year).
