Answer 1

The percent of decrease in the number of athletes finishing the marathon in Silvergrove is calculated by finding the difference in finishers, dividing by the original number, and converting to a percentage, which results in a 20 percent decrease.

Step-by-step explanation:

To calculate the percent of decrease in the number of athletes finishing a marathon in Silvergrove from last year to this year, we must follow these steps:

1. Find the difference in the number of finishers between the two years.
2. Divide the difference by the original number from last year.
3. Multiply the result by 100 to convert it to a percentage.

Step 1: The difference in the number of finishers is 7,580 subtracting 6,064, which equals 1,516 finishers.

Step 2: 1,516 divided by 7,580 equals approximately 0.2.

Step 3: 0.2 multiplied by 100 gives us a 20 percent decrease in the number of athletes finishing the marathon this year in Silvergrove.
