Tara's favorite cereals are sold in two grocery stores in her neighbourhood: Tom's market and Gianni's grocery store. A usual pack of this brand of cereal contains 25 oz. of cereal and is sold $I.5. A) Both stores decide to offer a special bargain on cereal. At Tom's market, the same pack of cereal is sold with 10% off. At Gianni's, the usual pack of cereal is replaced by a « special pack », that contains 10% more cereal. The « special pack » is sold for the same price. 1) How much does Tara pay for a pack of cereal at Tom's market? 2) Calculate the weight of cereal sold in a « special pack » at Gianni's. 3) Which store offers the best deal on cereal? 4) What if the usual pack of cereal was sold with 20% off at Tom's and the «special pack » sold at Gianni's contained 25% more cereal than the usual pack? B) Assume that Tom's market sells a pack of cereal with a% off and that Gianni's grocery store sells a « special pack » of cereal containing b% more cereal for the same price of $1.5. 1) Which conditions do a and b require for both stores to sell this brand of cereal at the same price per ounce? 07 2) Explain why this equation doesn't have any economically sensible solution for a = b.
