## Solving a Value Mixture Problem Using a Linear Equation

### Carmen's Coffee Shop

Carmen's Coffee Shop creates a blend that consists of two types of coffee. The following details describe the mixture:

- **Type A Coffee**: Costs $4.10 per pound.
- **Type B Coffee**: Costs $5.95 per pound.

This month's blend used four times as many pounds of Type B coffee as Type A, with a total cost of $641.70. The problem is to determine how many pounds of Type A coffee were used.

#### Task

Calculate the number of pounds of Type A coffee used.

**Solution Box:**
- [Input box for the number of pounds of Type A coffee]

- Buttons: X (clear), checkmark (submit answer), or help (? for hints).

To solve this problem, you would set up a linear equation based on the given information and solve for the unknown quantity, which is the number of pounds of Type A coffee.
