Question

Here is a story: Lin bought 4 bags of apples. Each bag had the same number of apples. After eating 1 apple from each bag, she had 28 apples left.

Which diagram best represents the story? Explain why the diagram represents it.
What part of the story does
x
represent?
Describe how you would find the unknown amount in the story​

Answer 1

Let's define the variable x as the number of apples in each bag.

We know that she bought 4 bags, then the total number of apples that she has is:

Apples = 4*x

Now she eats one apple for each bag, then she eats 4 apples, so she now has:

Apples = 4*x - 4

And we know that this is equal to 28, then:

4*x - 4 = 28

now we can solve this for x.

4*x = 28 + 4 = 32

x = 32/4 = 8

x = 8

There are 8 apples in each bag.

For the diagram part, by a small online search y found the image that you can see below.

The diagram that correctly represents this situation is diagram C, where x represents the number of apples in each bag.
