Question

Gabe goes to the mall. If n is the number of items he bought, the expression 18.9n + 24 gives the amount he spent in dollars at one store. Then he spent 28 at another store. Find the expression which represents the amount Gabe spent at the mall. Then estimate how much Gabe spent if he bought items.

Answer 1

The expression which represents the amount Gabe spent at the mall is 18.9n + 24 + 28 = 18.9n + 52.

If Gabe bought n = 10 items, then the amount he spent at the mall is 18.9 * 10 + 52 = 189 + 52 = 241 dollars.
