Concept:Annual rent expense is the monthly rent payable multiplied by 12 months.Explanation:Monthly rent payable = GH¢ 3,000.Annual rent expense = 3,000×12=36,000.This gives an annual rent expense of GH¢ 36,000.The rent paid of GH¢ 48,000 is more than the rent expense for the year.The excess amount is GH¢ 48,000−36,000=12,000.This excess is treated as prepaid rent.Therefore, the rent expense charged for 2018 is GH¢ 36,000.Answer:GH¢ 36,000 — Option C.
