Store A advertises a sale for 3 loaves of bread for $5.94. Explain how to use an equivalent rate to find the unit price of the bread at Store A.

1 answer

To find the unit price of the bread at Store A, you can use an equivalent rate approach. The unit price is the cost of one loaf of bread. Here’s how you can calculate it:

  1. Identify the total cost and the quantity: Store A is selling 3 loaves of bread for $5.94.

  2. Set up the equation for the unit price: The unit price (cost per loaf) can be calculated by dividing the total cost by the number of loaves. The formula looks like this: \[ \text{Unit Price} = \frac{\text{Total Cost}}{\text{Number of Loaves}} \]

  3. Substitute the values into the equation: \[ \text{Unit Price} = \frac{5.94}{3} \]

  4. Perform the division:

    • To calculate \( \frac{5.94}{3} \), you can do the division: \[ 5.94 \div 3 \approx 1.98 \]
  5. Interpret the result: The unit price of one loaf of bread at Store A is approximately $1.98.

By using this equivalent rate, you can easily find the cost per loaf of bread, making it easier to compare prices with other stores or sales.
