Given that Maya purchased a car on installment scheme for 9 months and she paid down payment of DHS$200, to determine what will be the total cost of the car if she pays installments of DHS$275.60 for 9 months, the following calculation must be performed:
200 + (275.60 x 9) = X
200 + 2,480.40 = X
2,680.40 = X
Thus, the total cost of the car would be DHS$2,680.40.
