The equation that represents the situation is:
Total number of cupcakes needed = Number of cupcakes already made + Number of cupcakes needed to be made
Let x be the number of cupcakes needed to be made.
The equation is then:
18 = 11 + x
To solve for x, we need to isolate it on one side of the equation.
Subtracting 11 from both sides, we get:
18 - 11 = x
7 = x
Therefore, you need to make 7 more cupcakes.
You need to make 18 cupcakes for a birthday party. You have already made 11. How many more cupcakes do you need to make? Write an equation and solve.
