The manager at the EdHelper Bank lost track of the total original investments that five people deposited into the bank.

Figure out the original deposit for each of these customers (David, Makayla, Mackenzie, Julia, and Justin). All of the accounts are paid simple annual interest.

1.    David's account, which pays 5.86%, will earn $329.75 more in simple interest than the simple interest earned in one year by Justin's account. Justin has an account that pays 5.67% annual interest. David and Justin originally deposited $17,000 altogether.

2.    Makayla and Julia deposited a total of $27,500 into two accounts. One account is paying 6.47% and the other is paying 6.14% simple interest. In one year, the annual simple interest will be $1,754.50 for both accounts.

3.    Mackenzie will earn $4.30 less simple annual interest than David. Mackenzie's annual interest rate is 7.95%.
