Answer

Yani originally paid $10 per box for his cereal, while the new super-saving brand costs $7 per box. The difference in price between the two brands is $10 – $7 = $3. Therefore, Yani’s original brand costs $3 more per box than the super-saving cereal. For Part B, if Yani buys 5 boxes of the new brand each month, his total expense for the super-saving cereal would be 5 boxes * $7/box = $35. In contrast, if he bought the original brand, it would cost him 5 boxes * $10/box = $50. The savings per month by switching to the super-saving brand amounts to $50 – $35 = $15. Thus, Yani saves $15 each month after switching brands.
