Question

Find the percent of increasea) Had 21 Now have 28

Answer 1

Answer:

33.3% increase

Explanation:

We'll use the below formula to determine the percent of increase;

$\text{Percent of increase = }\frac{Increase}{\text{Original Number}}\times100$

Given the original number as 21, we'll follow the below steps to determine the percent of increase;

Step 1: Find the difference between 21 and 28 which will be the increase;

$28-21=7$

Step 2: Substitute the increase which is 7 and the original number which is 21 into the above-stated formula and evaluate;

$\text{Percent of increase = }\frac{7}{21}\times100=\frac{1}{3}\times100=0.333\times100=33.3\text{\%}$
