A bakery buys flour for  $1.39 per pound. The bakery uses 80 pounds of flour for 5 days. At this rate, how much would the bakery spend on flour for 20 days?

To calculate how much the bakery will spend on flour for 20 days, follow these steps:

1. **Determine the amount of flour used per day**:
   - The bakery uses 80 pounds of flour for 5 days.
   - Flour used per day = $ \frac{80 \, \text{pounds}}{5 \, \text{days}} = 16 \, \text{pounds/day} $.

2. **Calculate the amount of flour used for 20 days**:
   - For 20 days, the bakery would use:
   \[
   16 \, \text{pounds/day} \times 20 \, \text{days} = 320 \, \text{pounds}
   \]

3. **Find the cost of 320 pounds of flour**:
   - The cost of flour per pound is $1.39.
   - Total cost = $ 320 \, \text{pounds} \times 1.39 \, \text{dollars/pound} $.
   \[
   \text{Total cost} = 444.80 \, \text{dollars}
   \]

Thus, the bakery would spend **$444.80** on flour for 20 days.
