D) Initial balance: $74, Deposit of $120

Answer 1

To find the balance in your account after each deposit or withdrawal, use the expression 'balance + deposit amount' for deposits and 'balance - withdrawal amount' for withdrawals.

Step-by-step explanation:

To find the balance in your account after each deposit or withdrawal, we can define a variable, let's call it 'balance'. The expression to find the balance after a deposit is 'balance + deposit amount', and after a withdrawal is 'balance - withdrawal amount'.

A) Initial balance: $74, Deposit of $18:
Balance after deposit = 74 + 18 = 92

B) Initial balance: $74, Withdrawal of $29:
Balance after withdrawal = 74 - 29 = 45

C) Initial balance: $74, Withdrawal of $147:
Balance after withdrawal = 74 - 147 = -73

D) Initial balance: $74, Deposit of $120:
Balance after deposit = 74 + 120 = 194
