Okay here is my question
two guys buy a new room for $10,000
down payment: $1000
and they want to pay whatever they owe in 30 monthly payments..
find the amount of the monthly payment at 10% add on interest.
I keep getting 330..
but the answer is 375.
I don't understand :/

Assistance needed.

my answer is correct.
could help me with my other question. 
I cannot  really! You don't want me helping you with math!!
But if you put the word MATH at the beginning of the subject line, you'll get the attention of a tutor or two who can.
