Debbi's new balance is $1,873.20, what increase in pay was direct deposited?
a. $803.18 b. S848.28
c. $867.50 d. $906.45

Answer 1

Option b.

Explanation:

The balance in Debbi's account in the start of the month was = His previous month's balance + Prevoius month's pay = $320.45 + $4300.5 = $4620.95

Now, total expenditure of this month = Pay check + ATM withdrawal + Service charge = $3290.78 + $300 + $5.25 = $3596.03.

So, the balance of this month will be $(4620.95 - 3596.03) =$1024.92

But Debbi's new balance is $1873.20.

Therefore, the increase in pay is $(1873.20 - 1024.92) = $848.28 was the direct deposit. (Answer)
