Mai borrowed $12,000 at 5% interest for 6 years.

What was the total interest Mai paid?

$

So if it is simple interest then

basically you are looking for the interest paid so

5%=5/100=0.05

assuming that the interest is calculated yearly

(12000 times 0.05) times 6 because 6 years so

if you calculate that out then you get 3600

Mai paid $3600 total
