Pamela bought four binders from a bookstore. Define the write two equivalent expression to reperesent the total cost.

4X

a+b+c+d

Step-by-step explanation:

Let the total cost = y

If the price of four binders are the same, then each will cost x dollars.

The total cost will be 4X

If the price are not the same, then total cost will be a+b+c+d

While a, b, c and d represent cost for each book.

4 (x) = t

t:4 = x
