Question

Last year, 15 dogs entered the local dog show. This year, 20 entered. What is the percent increase? (Hint: Percent of Change problem)(round to the nearest whole number)

Answer 1

To calculate the percent increase, find the difference between the new and original number of entries, divide by the original number, and multiply by 100. From 15 to 20 dogs, the percent increase is approximately 33% when rounded to the nearest whole number.

Step-by-step explanation:

The student is asking how to calculate the percent increase in the number of dogs that entered a local dog show from last year to this year. To find the percent increase, you subtract the original number of dogs from the new number and then divide by the original number. Finally, you multiply by 100 to get the percentage.

In this case, the number of dogs has increased from 15 to 20. So the increase is 20 - 15 = 5 dogs. To get the percent increase, you would then do the following calculation:

(5 dogs increase / 15 dogs original) × 100 = (1/3) × 100 ≈ 33.33%

Rounded to the nearest whole number, the percent increase in the number of dogs entered into the dog show is approximately 33%.
