From the information shown in the image:

Key Information:

1. 500 customers contacted the company today.
2. Contact breakdown:
   • Phone: 250 customers.
   • Email: 50% of the Phone contacts = $250 \times 0.5 = 125$.
   • Social Media: Denoted as a base value.
   • Webchat: 4 times the Social Media contacts.

Let us calculate the number of Social Media and Webchat contacts.

Step 1: Total Contacts Equation

The total contacts equation is: $\text{Phone} + \text{Email} + \text{Social Media} + \text{Webchat} = 500$

Substitute known values: $250 + 125 + x + 4x = 500$

Step 2: Simplify

$375 + 5x = 500$

Step 3: Solve for $x$ (Social Media contacts)

$5x = 125 \quad \Rightarrow \quad x = 25$

Step 4: Calculate Webchat contacts

$\text{Webchat} = 4 \times \text{Social Media} = 4 \times 25 = 100$

Final Breakdown:

• Phone: 250 contacts.
• Email: 125 contacts.
• Social Media: 25 contacts.
• Webchat: 100 contacts.

Pie Chart Percentages:

• Phone: $\frac{250}{500} \times 100 = 50\%$.
• Email: $\frac{125}{500} \times 100 = 25\%$.
• Social Media: $\frac{25}{500} \times 100 = 5\%$.
• Webchat: $\frac{100}{500} \times 100 = 20\%$.

Adjust the Pie Chart:

The pie chart should reflect the following percentages:

• Phone: 50%.
• Email: 25%.
• Social Media: 5%.
• Webchat: 20%.
