Question

On Saturday, the bookstore sold x books. On Sunday, the bookstore sold 2 more books than on Saturday.

Which expression represents the total number of books sold over the weekend?

2x

x + 2

2x + 2

2(x + 2)

Answer 1

x = books were sold on Saturday.

Because 2 more books were sold on Sunday than on Saturday, therefore
(x + 2) books were sold on Sunday.

The total number of books sold over the weekend (Saturday and Sunday) is
x + (x+2)
= x + x + 2
= 2x + 2

Answer: 2x + 2
