To solve the problem, let's calculate the total cost of the three items Pam wants to buy before applying the coupon, and then apply the 20% discount to find the final amount.

Step 1: Calculate the total cost before the discount:

• Shirt: $11.99
• Pants: $23.98
• Belt: $9.95

The total cost before the discount is: $11.99 + 23.98 + 9.95 = 45.92$

Step 2: Apply the 20% discount:

Pam has a coupon for 20% off, which means she pays 80% of the total price: $\text{Discounted cost} = 45.92 \times 0.80 = 36.736$ Rounding this to the nearest dollar, the total is approximately $37.

Thus, the correct answer is "About $37."

Would you like further details or have any questions? Here are five related questions:

1. How do you calculate a percentage discount on any total amount?
2. What is the meaning of rounding, and why is it applied in this case?
3. If Pam had a 30% coupon instead, how much would she pay?
4. How would tax affect the final price if there were a 7% sales tax?
5. How could you calculate the original price if you only knew the final discounted price and the discount percentage?

Tip: Always remember that applying a percentage discount means multiplying the total by 1 minus the discount percentage (e.g., for 20% off, multiply by 0.80).
