Answer:
He had $3.90 at the start of his walk.
Step-by-step explanation:
To find out how much money he had before his walk, you would take 2.55 + 1.35 and that you give you 3.9. But since we are dealing with money, you need to have the 0 at the end. So he started with $3.90 when he started his walk.
