Final answer:
To find the cost for 12 pounds of oranges, divide the cost of 5 pounds by 5 to find the cost per pound. Then, multiply the cost per pound by 12 to find the total cost for 12 pounds.
Step-by-step explanation:
To figure out the cost of 12 pounds of oranges, we need to determine the cost per pound. We can do this by finding the cost per pound for 5 pounds of oranges and then using that rate to calculate the cost for 12 pounds.
First, we divide the cost of 5 pounds of oranges ($11.55) by 5 to find the cost per pound. $11.55 / 5 = $2.31 per pound.
Next, we multiply the cost per pound ($2.31) by 12 to find the cost for 12 pounds of oranges. $2.31 * 12 = $27.72. Therefore, it would cost $27.72 for 12 pounds of oranges.
