Question

If Peter withdrew $47.27 from the bank and deposited $598, how would his bank account change? (Indicate how much his account would have increased or decreased)

Answer 1

Since we do not know the balance we should start with, a general answer:

`b_(new) = b_(old) + \sum_(i) d_(i) - \sum_(j) w_(j) \\`

598 - 47,27 = 550,73, assuming b_old was 0$ for your example

Explanation:

b stands for balance (old - before any deposits or withdrawals, new after all done)

d for deposits

w for withdrawals
