An arrangement has been made with the local bank that if CamDrone maintains a minimum balance of $$50,000$ in their bank account, they will be given a line of credit at a preferred rate of $3\%$ per annum $(0\mathrm{.}25\%$ per month$).$ All borrowing is considered to happen on the first day of the month, repayments are on the last day of the month. All borrowings and repayments from the bank should be in multiples of

$$10,000$ and interest must be paid at the end of each month. Interest is calculated on the balance at the beginning of the month, which includes any amounts borrowed that month.
