She is correct, first of all, to add 7/8 and 5/6; you must have common denominators so make 7/8 into 42/48 and make 5/6 into 40/48. Then just add them together now, and it will be 82/48. This when you divide 82/48 it will be 1 17/24. So, your answer is, yes, Kit is right.

1800 x 6 = 10800.
It will cost Samantha $10,800 to get her degree.
Notice that

, so

Then taking the positive square root gives

so
