To find that you first need to find what 9% is. You can multiply the number, 2,860 by .09 to find out your answer. That should be equal to 257.40. Since you now have that number, you can multiply it by 36. 257.40 is your average per month and you want to know by 3 years. So then your next step is 257.4*36 (there is 36 months in 3 years) which should be equal to 9,266.40.

If you would like to know what is the answer for 6 - 7/8, you can calculate this using the following steps:
6 - 7/8 = 48/8 - 7/8 = (48 - 7) / 8 = 41/8 = 5 1/8 = 5.125
The correct result would be 41/8 or 5 1/8.
See "intersecting secants theorem" (you should be able to find a variant that specifically applies to arc measures). It says that for this circle,
