Zachary can spend no more than $94 per day to rent a car.  A car rents for $30 per day plus $0.20 per mile.  Write an inequality for this situation and solve.

• .20m + 30 ≥ 94; m ≥ 320
• .20m + 30 > 94; m > 320
• .20m + 30 ≤ 94; m ≤ 320
• .20m + 30 < 94; m < 320

Carefully examine the work in the image.  Whose solution is incorrect?  What mistake was made?

• Kevin; The Distributive Property was used incorrectly.
• Stephanie; The Commutative Property was used incorrectly.
• Both Kevin and Stephanie; The Associative Property was used incorrectly.
