The price of an item in a shopping cart is c dollars. If the sales tax on the item is 9%, and the expression c + 0.09c represents the total cost of the item after tax, which TWO EXPRESSIONS also represent the total cost of the item after tax? A) 0.9c
B) 1.09c
C) 1.9c
D) (1 – 0.09)c
E) (1 + 0.09)c

If you factor c + 0.09c, we get c(1 + 0.09), which is the same as (1 + 0.09)c.

If we add the numbers inside the parentheses (1 + 0.09)c we get 1.09c.
