Show your work.Part B: How much money does Yani save each month with the change in cereal brand if he buys 5 cereal boxes each month? Show your work.

Step-by-step explanation:Part A: The price of the first cereal that Yani bought was $10 and he new cereal is $7.
$10 - $7 = $3. The original box of cereal was $3 more than the super- saving cereal.
Part B: Yani will save $15 each month. With the $10 cereal he used to pay $50 per month. Now with the super-saving cereal, he will now pay $35 per month. So we need to subtract $50 - $35 = $15
