First work out total amount repayable.
You have the loan (100%) and the interest payments for 2 YEARS (12 * 2 = 24%). Add them together and you get 124%.
£7500 / 100 = £75 (1%)
(* 124)
= £9300 REPAYABLE (124%)
2 Years = 24 Months
£9300 / 24 = £387.50.
Monthly repayments will be £387.50
In from U.K. so used the pound sign, just change back to dollars.
Hope this helped
