Question

write and simplify an expression to find the total cost of X pencils one poster board and one notebook​

Answer 1

Answer:

xp + b + n

Step-by-step explanation:

Let "x" represent the amount of pencils needed to be bought

Let "p" represent the cost of 1 pencil

Let "b" represent the cost of one poster board

Let "n" represent the cost of one notebook

Since there is only one poster board and notebook being bought, they do not need a variable in front of their cost.
