Hi expert, could you please help me with this

If Patricia asks Katie and Pete to repay the loan ($30, 000) as an annual equal amount at the end of each year over the 10-year period based on the annual rate of interest calculated from a(i) which is 5%, how much would the annual repayment be? What is the total cash repayment for the loan over the period? How much interest would they have paid on the loan.
