Question 1035247
the old price is 7.20
the new price is 9.20


the increase over the old price is equal to new price - old price = 9.20 - 7.20 = 2.00.


the ratio of the increase to the old price is 2.00 / 7.20 = .277777778


in fraction form, that is equal to 5/18.


what this says is that the increase in price over the old price is equal to 5/18 * the old price.


5/18 * 7.20 = 2.00
