Question

Martin has an 18-cup container of flour that he uses for muffins only. He uses 3 cups of the flour for every batch of muffins he makes. Write an equation to show how much flower is left in the container after x batches of muffins.

Answer 1

If f stands for flour left, then 18-3x=f

Answer 2

`y=18-x`

Explanation:

Let x be the no. of batches of muffins

Each batch requires cup of flour = 3

So, No. of cups required for x batches = 3x

Martin has an 18-cup container of flour that he uses for muffins only.

So, remaining flour = 18 - 3x

Let y denotes the cups of remaining flour

So,
`y=18-x`

So, an equation to show how much flower is left in the container after x batches of muffins is
`y=18-x`
