Answer:

13 cents, 17 cents, Brand A

Step-by-step explanation:

The unit price is the price of a single pencil. You can find that by dividing the total price by the number of pencils.

Brand A= $2.36/18= $0.13

Band B= $4.09/24= $0.17

0.13 < 0.17

Brand A is cheaper because the price per pencil is less.
