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.
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.
To find out how many more cupcakes you need to make, we can set up an equation. Let's call the number of cupcakes you need to make as 'x'.
The total number of cupcakes you need is 18, and you have already made 11 cupcakes. So, the equation will be:
11 + x = 18
To solve for 'x', subtract 11 from both sides of the equation:
11 + x - 11 = 18 - 11
Which simplifies to:
x = 7
Therefore, you need to make 7 more cupcakes for the birthday party.
