You deposited money in a savings account paying 4% simple interest per year. the first year, you earned $75 in interest. how much interest will you earn during the following year?

There's simple interest and there's also compound interest.

the difference is that, with simple interest, what you earn is a percentage of the "original amount you deposited", so if you deposited say 1000 and you earn 10% APR, you only get 100 bucks a year, 1st, 2nd, 3rd 20th year, no matter what year it may be, is always 10% of that original 1000.

so, in short, if you earned 75 bucks in the first year, well, for simple interest, that won't change for any subsequent year.

It might be "an artistic taste"  hope i !
