3.) Mr. Richards and Mr. Dolge each began improving their yards over the summer by buying bags of soil (fancy dirt) and bags of mulch (bark dust). Since Mr. Dolge has access to a truck, Mr. Richards got a ride and as a result they got their supplies from the same store. Mr. Dolge spent $97 on 3 bags of soil and 14 bags of mulch. Mr. Richards got 14 bags of soil and 7 bags of mulch for $161. They forgot to get a receipt, but just in case they need more supplies, they are wondering how much each bag of soil will cost, and how much each bag of mulch will cost. What should they find these prices to be?
2. Jimmy was drawing rectangles at his desk. After a while he concluded that if you increased one of the sides by 10% and decrease the other side by 10% the area won't change. Is Jimmy correct? Provide a formal mathematical argument as well as a "teacher response" to Jimmy.
