If i want to earn $100 on a 3-month cd that pays 4% annual simple interest, how much must i invest?

keeping in mind that 3 months is not even a year, but since there are 12 months in a year, 3 months is really 3/12 years, therefore,

i got 86 for this

hope this !

if you need an explanation just ask
