1. **State the problem:** We know that 6 kg of sprouts costs 1.98. We want to find the cost of an 8 kg bag of sprouts if the cost per kg remains the same. 2. **Find the cost per kg:** The cost per kg is given by dividing the total cost by the weight in kg. $$\text{Cost per kg} = \frac{1.98}{6}$$ 3. **Calculate the cost per kg:** $$\frac{1.98}{6} = 0.33$$ So, the cost per kg is 0.33. 4. **Find the cost of 8 kg:** Multiply the cost per kg by 8. $$\text{Cost of 8 kg} = 0.33 \times 8$$ 5. **Calculate the total cost:** $$0.33 \times 8 = 2.64$$ 6. **Answer:** The cost of an 8 kg bag of sprouts, at the same cost per kg, is 2.64.
