An invoice for $450 has terms 2/10, 1/30, n/60. If you pay on the eighth day, how much will you remit? A. $446.00 B. $450.00 C.

elena-s [515]

I believe the answer is: C. $441.00

the terms 2/10, 1/30, n/60. indicates that you would get 2% discount if you pay within 10 days and 1% discount if you pay within 30 days.

If you pay on the 8th day, the amount of your payment would be:

$ 450 x 98% = $ 441
