Final answer:
The average cost of 1 pound of bananas, when a bunch weighing 2.4 pounds sells for $1.29, is calculated by dividing the total cost by the weight, resulting in approximately $0.54 per pound.
Step-by-step explanation:
The question asks us to calculate the average cost of 1 pound of bananas when a bunch that weighs 2.4 pounds sells for $1.29. To find this, we divide the total price of the bunch by the weight in pounds to get the price per pound.
Here is the calculation step by step:
- Write down the total cost of a bunch of bananas: $1.29.
- Write down the total weight of the bunch: 2.4 pounds.
- Divide the total cost by the total weight to find the cost per pound: $1.29 / 2.4 pounds.
- Do the division to get the average cost per pound: $0.54 (rounded to two decimal places).
Therefore, the average cost of 1 pound of bananas is approximately $0.54.
