Final answer:
To find the cost of 68 erasers, divide the cost of a package of 6 erasers by 6, and multiply it by 68.
Step-by-step explanation:
To find the cost of 68 erasers, we need to determine the cost of 1 eraser and then multiply it by 68. We know that a package of 6 erasers costs $0.39. Therefore, the cost of 1 eraser is $0.39 divided by 6.
To find the cost of 68 erasers, we multiply the cost of 1 eraser by 68. So, the cost of 68 erasers would be ($0.39 ÷ 6) × 68.
Performing the calculation, we get the cost of 68 erasers to be $4.46.
