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
Yani's super saving cereal is $3 less than the old brand cereal , and she saves $15 each month.
What is a Function ?
Function is an expression which relates two variables , an independent and a dependent variable.
It is given that
Yani buys a certain brand of cereal that costs $10 per box.
Yani changes to a super-saving brand of the same size.
The equation shows the price, y, as a function of the number of boxes, x, for the new brand.
y = 7x
For 1 box the price is $7
Part A: How many more dollars is the price of a box of Yani's original brand of cereal than the price of a box of the super-saving cereal
It is $ 10-7
$3
Part B: How much money does Yani save each month with the change in cereal brand if he buys 5 cereal boxes each month?
If Yani buys the old brand cereals , the cost would be 5*$10 = $50
The new cereal boxes will have cost 5*$7 = 35
Yani will save
$50 - $35
=$15
Therefore Yani will save $15.
