Answer:
The percent of increase in height of the stalks is 20%.
Step-by-step explanation:
The general formula for a percent increase is as follows: (Original Amount - New Amount/Original Amount) x 100. The original height of the stalks was 60 inches tall. The new height of the stalks is 72 inches. In the numerator of our fraction, we take 72-60 to get 12. Our denominator is the original amount, or 60. This gives us an overall fraction of 12/60, which when we divide gives us 0.2. Once we multiply our decimal by 100, we get an overall percent increase of 20%.
