Stephanie has $300, she puts it in the bank that gives 7.5% intrest how much will she have in 3 months?
Not enough information. 7.5% APR or APY? How often is the interest compounded?
Of course it is against the TOU for anyone to answer your homework questions but my questions might steer you in the right direction.
with ten years of banking under my belt we would need to know when the intrest is given. And if you are saying it is monthly then don't forget that each month her balance has grown.
she'll have $305.625 in 3 months. In a year, she woulda increased by $22.5 and then divide that by 4 is the amount she'ss gain in 3 months.
...the bank gives 7.5% interest over HOW MUCH TIME? Monthly? Annually?
