Question

If the original quantity is 15 and the new quantity is 18 ​, what is the percent​ increase?

Answer 1

The percent increase from an original quantity of 15 to a new quantity of 18 is calculated as ((18 - 15) / 15) × 100%, resulting in a 20% increase.

Step-by-step explanation:

To calculate the percent increase from an original quantity to a new quantity, you can use the following formula:

Percent Increase = ((New Quantity - Original Quantity) / Original Quantity) × 100%

Using the given numbers:

• Original Quantity = 15
• New Quantity = 18

The calculation would be:

Percent Increase = ((18 - 15) / 15) × 100% = (3 / 15) × 100% = 0.2 × 100% = 20%

Therefore, the percent increase is 20%.
