Answer:

Debit of $ 1.31

Step-by-step explanation:

Here, the initial amount in the account = $ 825,

Monthly interest on the amount = 0.75 % of initial amount

[tex]=\frac{825\times 0.75}{100}[/tex]

[tex]=\frac{618.75}{100}[/tex]

[tex]=$ 6.1875[/tex]

And, the service charge = $ 7.50,

Thus, the final amount = Initial amount + Monthly interest - Service charge

= $ 825 + $ 6.1875 - $ 7.50,

= $ 823.6875

So, the total changes in the amount = final amount - Initial amount

= $ 823.6875 - $ 825 = -1.3125 ≈ - 1.31

Since, negative sign shows the amount is debited,

Hence, the amount of debit to his account is $ 1.31.
