Depositing Money (Real-world examples using inverse operations: addition equations)

The video tutorial explains how to solve a real-world problem involving a bank deposit using algebra. It begins with a scenario where Kate deposits $45 into her bank account, resulting in a total of $250. The tutorial guides viewers through defining a variable to represent the unknown initial amount, setting up an equation, and solving it using inverse operations. The solution is verified by substituting the value back into the equation. The lesson concludes by emphasizing the use of inverse operations to solve mathematical problems.

What was the total amount in Kate's account after she deposited the money she earned from babysitting?

• $295.00

• $45.00

• $250.00

• $205.00

Which variable is used to represent the amount of money in Kate's account before the deposit?

• D

• A

• B

• C

What equation represents the situation of Kate's bank deposit?

• B - 45 = 250

• B + 45 = 205

• B = 250 - 45

• B + 45 = 250

What operation is used to solve the equation B + 45 = 250?

• Addition

• Multiplication

• Subtraction

• Division
