It's an 11% increase. To find this, you have to subtract 85 from 94.35 and then you divide that difference by the original amount. In this case it's 85. After that, you get .11. Then you just turn it into a percent.
"A student" doesn't register for 46,140 credits, unless he wants to be very very busy.
If ALL of the students on campus register for 46,140 credits, then many colleges
would estimate the number of full-time students by using the formula
f = n / 15 = 46,140 / 15 = <u>3,076</u> students.
That's not the formula for 'n'. 'n' is the total number of credits for the semester,
and the question tells you what 'n' is. Knowing 'n', the formula helps you find 'f'.
16 × 6.7 = 107.2
your answer is 107.2
