Marco’s bank statement says that he has an ending balance of $81. What is Marco’s starting balance?
natali 33 [55]

Answer:

$255

Step-by-step explanation:

Using the information provided, in order to find Marco's starting balance we simply need to add all of his transaction costs together. Once we have this value we simply add it to his ending balance amount which will give us the total dollar value of his starting balance.

20 + 22 + 13 + 39 + 34 + 15 + 31 = 174

174 + 81 = $255

Finally, we can see that Marco's starting balance was a total of $255
