Question
**Problem Statement:**

Payton is making stuffed animal keychains out of yarn. She set up an Etsy page to sell her keychains, and that cost her $32 to set up. Each keychain she makes requires $1.50 worth of yarn. She decides to sell each keychain for $8. 

**Question:**

What is the total cost function that Payton will need to pay for?

**Explanation:**

To calculate the total cost function that Payton will need to pay for, we need to factor in both the fixed cost and the variable cost:

1. **Fixed Cost:** This is the one-time setup fee for the Etsy page, which is $32.
2. **Variable Cost:** This is the cost of materials (yarn) for each keychain. Payton requires $1.50 worth of yarn per keychain.

**Total Cost** (C) can be expressed as a function of the number of keychains (x) Payton makes.

\[ C(x) = \text{Fixed Cost} + (\text{Variable Cost per Keychain} \times \text{Number of Keychains}) \]

Given the fixed cost is $32 and the variable cost per keychain is $1.50, the cost function becomes:

\[ C(x) = 32 + 1.50x \]

This function will help Payton determine her total costs based on the number of keychains she decides to make.
