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. (1 point) Responses 12 more cupcakes 12 more cupcakes 8 more cupcakes 8 more cupcakes 7 more cupcakes 7 more cupcakes 11 more cupcakes
The equation to solve this problem is: 18 - 11 = x, where x represents the number of cupcakes that still need to be made.
Simplifying the equation, we have: 7 = x.
Therefore, you need to make 7 more cupcakes.
To solve this problem, we need to subtract the number of cupcakes already made from the total number of cupcakes needed.
Let's denote the total number of cupcakes needed as "x".
The equation can be written as:
x - 11 = 18
To solve for x, we can add 11 to both sides of the equation:
x = 18 + 11
Simplifying the right side:
x = 29
Therefore, you need to make 29 cupcakes in total. Since you have already made 11, you need to make an additional 29 - 11 = 18 cupcakes.
To determine how many more cupcakes you need to make, you can use subtraction.
Step 1: Write an equation
Let "x" represent the number of cupcakes you need to make.
11 + x = 18
Step 2: Solve the equation
To solve for "x", isolate it on one side of the equation by subtracting 11 from both sides.
11 + x - 11 = 18 - 11
x = 7
Therefore, you need to make 7 more cupcakes for the birthday party.
