Martin has an 18 cup container of flour that he uses for muffins only. He uses 3 cups of flour for every batch of muffins he makes. Write any Quetion to show how much flower is left in the container after X batches of muffins. Then graph the function

We know that Martin has 18 cups of flour, and he needs 3 cups for each muffin.

Then, if he makes X muffins, the number of cups of flour that he needs is:

X*3 cups.

Then, if we subtract this number to the initial number of cups, we obtain the number of cups that he has before he makes X muffins:

N (X) = 18 - X*3

this defines a linear function, that has a y-intercept of 18, and has an x-intercept of 6, because:

N (6) = 18 - 6*3 = 0

which means that after he makes 6 muffins, he no longer has flour left.

6

Step-by-step explanation:

3 times 6=18 or6 times 3=18
