Answer: $0.28 per pencil
Step-by-step explanation: Unit price means the cost per unit, in this case the cost per per pencil.
Since we know that it costs $2.24 for 8 pencils, to find the cost for 1 pencil, we need to divide 8 into $2.24.
I provided an image with the division. *You can also just use a calculator.*
So, 8 divides into 2.24 0.28 times.
Therefore, each pencil costs 28 cents which means that the unit price is 28 cents per pencil.
