Choose an expression that would result in the total cost using addition. WRITE THIS DOWN, AS YOU WILL BE USING IT TO SOLVE THIS PROBLEM AND TURN IN TO ME TODAY! I'm using 'x', but you can use whatever variable you chose in problem 1

(This will be the first form to represent the situation)

• x + x - .50x

• x + x + .50x

• 2x - .50x

• None of these will work
