Let's Do Math!   Maria went shopping for a birthday gift for Cassie. In two different stores she saw the following signs.

 

Lots-of-Fun 3 for $4.89	Toys, Toys, Toys $2.29 Buy one at regular price, Get second at 1/2 price.
When Maria saw the sign in Toys, Toys, Toys, she thought, "This is great. I can get Cassie a stuffed animal and buy myself one for half price." What do you think of Maria's plan? Explain in the box below (And yes, you can purchase one or two bears at Lots-of-Fun at that same price.)
