Caleb makes a deposit of $25 in his checking account. His balance after the deposit is $0. He uses a number line to represent the amount of his deposit and his balance before the deposit. Where would the two points be located on the number line? Plot the points on the number line.

Solution :

In the context, it is given that Caleb deposits some amount of money in his checking account. And after the deposit he is having no money in his account i.e. $0 as balance in his account. So he must be his balance as negative in his checking account.  Accordingly, before deposit, Caleb had a balance amount of -$25 in his checking account. He deposited $25 to his account, so after the deposit, his balance in the account is $0.

Caleb uses a number line to represent his deposit and the balance before the deposit made.
