Dr. Piegan treated 440 dogs. The percentage of obese dogs increased from 52.5 percent in 2010 to 55.0 percent in 2011. What was the percent increase?

Sagot :

Well, the formula for finding percent change is [tex] \frac{amount of change}{original amount} [/tex] . So, the amount of change is 2.5 and original amount is 52.5. Then, to get the percent increase, you divide 2.5 by 52.5 which is 0.047619048. You multiply by 100 since its percent and get 4.7619048. But you should probably round to the nearest tenth ≈ 4.8%.
