Question

a carnival had 2,280 visitors this month, and 3,800 visitors last month. what was the percent decrease in the number of visitors?
label the double number line to represent this problem.
visitors
0 2,280 3800
0%

Explanation:

Step1: Calculate visitor decrease

$3800 - 2280 = 1520$

Step2: Find percent decrease

$\text{Percent Decrease} = \frac{1520}{3800} \times 100\%$

Step3: Simplify the calculation

$\frac{1520}{3800} = 0.4$, so $0.4 \times 100\% = 40\%$

Step4: Label the number line

First, find the percentage for 2280 visitors: $100\% - 40\% = 60\%$.

• The box under 2280 corresponds to 60%
• The box under 3800 corresponds to 100%

Answer:

The percent decrease in visitors is 40%.
For the double number line:

• The box below 2280 is filled with 60%
• The box below 3800 is filled with 100%
