To represent the total change to John's account for the transactions he made, we need to consider how each transaction affects his account balance.

  1. Withdrawing $55 from the ATM means his account decreases by $55. This can be represented as -$55.
  2. Writing a check for $18 means his account decreases by $18 as well. This can be represented as -$18.

To find the total change to John's account, we sum these changes:

\[ -55 + (-18) \]

This simplifies to:

\[ -55 - 18 = -73 \]

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

\[ -55 + (-18) = -73 \]

Therefore, the correct response is:

\[ -55 + (-18) = -73 \]
