Azmir's checking account pays 0.75% interest monthly and has a $7.50 service fee. If Azmir's balance last month was $825, find t
svetlana [45]

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

=\frac{825\times 0.75}{100}

=\frac{618.75}{100}

=$ 6.1875

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.

What is 2.26 (6 repeating) as a fraction?
Gekata [30.6K]

Answer:

34/15

Step-by-step explanation:

I recognized the form of this decimal as a number divided by 3. However, when I multiplied it by 3, I got 6.8. This means that the fraction was not fully simplified. Multiplying by 5, I got 34. Since I had to multiply by 3 and then by 5 to get there, I multiplied by a total of 15. Hope this helps!
