Final answer:
To find the unit price per 100 grams of bread when 300 grams cost $3.30, divide the total cost by 3. The unit price is $1.10 per 100 grams.
Step-by-step explanation:
The question asks us to find the unit price per 100 grams of bread given that the price for 300 grams is $3.30. To calculate the unit price, we divide the total cost by the number of units to find the cost per unit. Here's the calculation:
- Total price for 300 grams = $3.30
- Unit price per 100 grams = Total price ÷ 3
- Unit price per 100 grams = $3.30 ÷ 3
- Unit price per 100 grams = $1.10
Therefore, the unit price per 100 grams of bread is $1.10.
