Making Cupcakes (Real-world examples using inverse operations: multiplication equations)

The video tutorial explains how Luka used 4 boxes of cake mix to make 96 cupcakes and seeks to find how many cupcakes one box yields. The process involves defining a variable, setting up an equation, and using inverse operations to solve it. The solution is verified by substituting back into the equation, confirming that each box yields 24 cupcakes. The lesson demonstrates solving real-world math problems using inverse operations.

Luka used 4 boxes of cake mix to make a certain number of cupcakes. How many cupcakes did he make in total?

• 24

• 96

• 48

• 120

What variable is used to represent the number of cupcakes per box in the equation?

• c

• n

• b

• x

Which equation correctly represents the relationship between the number of boxes and the total cupcakes?

• b - 4 = 96

• b/4 = 96

• 4b = 96

• 4 + b = 96

What operation is used to solve the equation 4b = 96?

• Multiplication

• Subtraction

• Addition

• Division

How many cupcakes does one box of cake mix yield?

• 48

• 24
