To find the total change in Sam's bank account, we can calculate the net change by subtracting the amount withdrawn from the amount deposited.
- Sam withdrew $180, which is a negative change in his account.
- He then deposited $430, which is a positive change in his account.
Now, we calculate the total change:
\[ \text{Total change} = \text{Amount deposited} - \text{Amount withdrawn} \] \[ \text{Total change} = 430 - 180 = 250 \]
So, the total change in Sam's bank account is $250.
