Question

At the beginning of the month Kiran had $24 in his school cafeteria account. Use a variable to represent the unknown quantity in each transaction below and write an equation to represent it. Then, represent each transaction on a number line. What is the unknown quantity in each case? 1. In the first week he spent $16 on lunches. How much was in his account then? 2. Then he deposited some more money and his account balance was $28. How much did he deposit? 3. Then he spent $34 on lunches the next week. How much was in his account then? 4. Then he deposited enough money to pay off his debt to the cafeteria, How much did he deposit? 5. Explain why it makes sense to use a negative number to represent Kiran's account balance when he owes money.​

Answer 1

Because it means that person Deposited that much that they didn't have so meaning when they add new money the negative number something of the amount will be taken away.

An Example is a person has in their bank account 20 dollars. They Spent 25 dollars so then means they owe the bank 5 dollars so it's gonna be -5.
