## anonymous 3 years ago Hi everyone, would someone be able to help me with the following: Exact Interest for Principle of $3400, Rate is 11% and Time is 176 Days. I keep getting$179.52 which is not a choice on my homework. Any help is greatly appreciated, denise

Rate = I/PT. That I can figure but somewhere I am messing up, thanks again, denise PS Exact interest is used as 365 days, I've been doing that part right too, I think, lol!

Oh lord, I'm too tired, I messed up the formula I see

11% means that someone will obtain $3400*0.11=$374 in a year. But 176 days is a $$\frac{176}{365}=0.482$$ part of the year. So it will be $374*0.482=$180,268.

3400 X .11 X .482 ?
