Profit percentage are used to refer to the amount of profit that has been incurred in terms of percentage. It should also be stated that the profit percentage is one of the methods for comparing two quantities which the shopkeeper gets a profit.
How to calculate percent increase of the given product ?
It is given that Iceberg lettuce is grown and shipped to stores for about 30 cents a head and consumers purchase it for about 72 cents a head.
Thus cost price of the product is 30 cents whereas the selling price is 72 cents.
Therefore, profit incurred is = (72 - 30) = 42 cents.
Percent increase -
= (profit / cost price) * 100 %
= (42/30) * 100 %
= 140 %
Thus, the percent increase in sales of Iceberg lettuce is 140% .

In this case, 72-30 = 42
42/30 = 7/5
7/5 x 100 = 140%
I hope this makes sense!
