A customer withdrew $100 from a bank account. The customer then deposited $33 the next day. Write and then evaluate an expression to show the net effect of these transactions.

Deposits are positive since we add money

So we have:

• 100 withdrawal = -100
• 33 deposit = +33

Our balance is:
-100 + 33 = -67 net
