Joan was advanced $3$ loans: $$6158\mathrm{.}29$ at the start of January, $$8309\mathrm{.}83$ at the start of February and $$9163\mathrm{.}98$ at the start of April. She expects to repay these debts with three equal payments: one at the start of September, one at the start of October and one at the start of December. Suppose the rate of interest is $3\mathrm{.}40\%.$ Use the start of October as a focal date.

What is the value of the first loan at the focal date?
