Question

A box of snacks contains 20 individual packages. The new design packages 28 individual packages. By what percentage do the number of individual packages increase?

Answer 1

The number of individual packages increases by 40%.

Step-by-step explanation:

To find the percentage increase in the number of individual packages, we need to calculate the difference between the new number of packages and the old number of packages, and then divide that difference by the old number of packages. Finally, multiply the result by 100 to convert it to a percentage.

Let's say the old number of individual packages is 20, and the new number is 28.

Using the formula: Percentage Increase = ((New Value - Old Value) / Old Value) * 100

Percentage Increase = ((28 - 20) / 20) * 100 = 40%

Therefore, the number of individual packages increases by 40%.
