John used his debit card to withdraw $55 from the ATM. Then, he wrote a check for $18.00. Which equation represents the total change to John's account for these two transactions?

Answer 1

To determine the total change to John's account due to the two transactions, we need to account for the withdrawal from the ATM and the check written.

1. Withdrawing $55 from the ATM is a decrease in John's account, so we represent this as \(-55\).
2. Writing a check for $18.00 is also a decrease in John's account, so we represent this as \(-18\).

To find the total change to John's account, we can add these two amounts together:

\[ \text{Total Change} = -55 - 18 \]

So, the equation that represents the total change to John's account for these two transactions is:

\[ \text{Total Change} = -55 - 18 \]

This can also be simplified to:

\[ \text{Total Change} = -73 \]

Thus, John's account decreases by a total of $73 due to these transactions.
