Hi there! So I was doing my practice exams and I got this question:
I feel so dumb. I really floundered, though I got the right answer. I did the following steps:
NAV x shares = 3,105
And then I tried to do:
3,105 / 99.75 (100-.25 in this case.)
And that didn’t give an applicable answer. I then tried to multiply it instead and I got an answer I could chose for the question.
I’m sure the answer is very simple, I just am so confused.
Hi @StormiSkies! Making mistakes is part of the learning process 
The main point is that mutual funds are redeemed at the NAV, minus the redemption fee.
Facts in the question:
The NAV x shares = $3,105, as you had, but we still haven’t subtracted the redemption fee. The redemption fee is a fee the investor pays when they redeem the fee, so even if we make a mistake in the math calculating it, the amount they receive must be less than the total amount of $3,105.
100% - 0.25% = 99.75%, as you had. Multiplying the total amount ($3,105) by the percent the investor receives after paying the 0.25% fee (99.75%) gives you the amount they receive ($3,105 * .9975 = $3,097.2375).
Another way to think about it is that the redemption fee, expressed in dollars, is ($3,105 * .0025 = $7.7625). If you subtract that from the total amount, you end up with the same value ($3,105 - $7.7625 = $3097.2375).
