Megan bot seven charms for Thirty-one dollars and fifty cents. Each charm costs the same amount of money.

Write an inequality that can be used to find the maximum amount of charms Megan can buy $75

First solve the price of each charm

$ 31.5 = 7x

X = 31.5 / 7

X = $ 4.5 / charm

So the maximum amount of charms megan can buy for $ 75 is

Y = $ 75 / $ 4.5 per charm

Y = 16.67 charm since there are no fraction of a charm

Then y < 16.67 charms
