Last year, Scout Troop # 85 sold 540 boxes of cookies. This year, they sold 783 boxes.What was the percent increase in the number of boxes sold?

783-540 and then divide that answer by 540 to get a decimal. Change the decimal to a percent.

45

To find the percent increase in the number of boxes sold, you need to calculate the difference between the number of boxes sold this year and last year, and then divide that difference by the number of boxes sold last year. Finally, multiply the result by 100 to convert it into a percentage.

Let's calculate it step by step:

Step 1: Calculate the difference between the number of boxes sold this year and last year
Difference = Number of boxes sold this year - Number of boxes sold last year
Difference = 783 - 540
Difference = 243

Step 2: Divide the difference by the number of boxes sold last year
Percent Increase = (Difference / Number of boxes sold last year) * 100
Percent Increase = (243 / 540) * 100
Percent Increase ≈ 45%

Therefore, the percent increase in the number of boxes sold is approximately 45%.
