Alright so 25% of the 32 students scored an A. 25% is equal to 1/4. So just take a fourth of 32 to get your answer, which is 8.
$2500 is what % of $17,500
$2500 = n% x $17,500
Well our problem now is that we can move the decimal back two places on a percent that we do not yet know.
However we can move it back on the number we are multiplying n% by.
Here's why: Sample: .67 x 52 = 67 x .52 the answer are the same even though I switched the decimal points.
So
2500 = 175n ($17500 moved back two places)
You get about 14.28% (rounded to the nearest hundredth of a percent)
Alternative method:

= .1428 (number goes on for 6 digits and then repeats) .1428 = 14.28%
Five less than a number n
