9. 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?(1 point)

Responses

55−18 = 37
55−18 = 37

−55 + (−18) = −73
−55 + (−18) = −73

-55 + 18 = -37
-55 + 18 = -37

55 - (-18) = 73
55 - (-18) = 73
