State the domain of the relation (1,2,3,3,4,5) (-3,-1,1,2,3)

Unitary pencil cost= $2.06

Step-by-step explanation:

Giving the following information:

Total cost= $22.35

Pad cost= $9.99

Number of pencils= 6

First, we need to calculate the total cost spend on pencils.

Total pencils cost= total cost - pad cost

Total pencils cost= 22.35 - 9.99

Total pencils cost= $12.36

Now, the cost of each pencil:

Unitary pencil cost= 12.36/6

Unitary pencil cost= $2.06
