Which situation involving Raul’s bank account would be modeled by a positive number?

Question

Raul deposited his paycheck.
Raul wrote a check to his grandmother.
Raul withdrew cash from an ATM.
Raul paid for groceries with his debit card.

Answer 1

The situation involving Raul's bank account that would be modeled by a positive number is:

Raul deposited his paycheck.

This action increases the balance in his bank account, which is represented by a positive number. The other situations (writing a check, withdrawing cash, and paying for groceries) would result in negative changes to his account balance.
