Yeah sure! No problem. Let us begin.

Hey, Anne!Is it okay if I ask you to assist me with my homework? It's about giving a real-life example of direct variation.

So, the first step that we are going to do is to write the right equation and that direct variations are solved using the equation, y = kx. Right?

Yes! You are right. Then, You use the information given in the problem to find the value of k. In this case, you need to find k when x = 2 and y = 7.

what's the next step?

Rewrite the equation from step 1 substituting in the value of y found in step 2.

After doing the step 2, We can now proceed directly to solving the problem.



Then what's the solution and answer?

Meaning to say, we can make 56 cupcakes. I get it now. Thank you, Anne!

You're welcome.

A recipe for 7 cupcakes needs 2 cups of flour. The number of cupcakes you can make varies directly with the amount of flour. How many cupcakes can you make with 4 cups of flour?
