Question

Harmony earns a $42,000 salary in the first year of her career. Each year, she gets a 4%, percent raise.

Which expression gives the total amount Harmony has earned in her first n years of her career?

Answer 1

42000*1.04^(n-1)

Explanation:

4% is equal to 0.04, a raise is 1+0.04=1.04

1.04 is now the number we are multiplying by to get a new yearly salary for Harmony.

42000*1.04^(n-1) since n is how many years after she has the job you have to raise it to the power and subtract one.
