Bread cost 607 pounds. It decreased in value by 9.4%. What does it cost now?

To find the new cost of the bread after a 9.4% decrease, we can follow these steps:

1. **Find the decrease amount:**
   \[
   \text{Decrease} = \text{Original cost} \times \frac{\text{Percentage decrease}}{100}
   \]
   \[
   \text{Decrease} = 607 \times \frac{9.4}{100} = 607 \times 0.094 = 57.058
   \]

2. **Subtract the decrease from the original cost:**
   \[
   \text{New cost} = \text{Original cost} - \text{Decrease}
   \]
   \[
   \text{New cost} = 607 - 57.058 = 549.942
   \]

Thus, the new cost of the bread is approximately **549.94 pounds**.
