Answer:

See below.

Step-by-step explanation:

Part A

"y = 11x is the function for the original boxes that he bought...it was $11 per box.

y = 9x is the function for the super saving brand...it is $9 per box

so there is a $2 difference between the original and the super saver."

Part B

"original box.....6 cereals

y = 11(6)

y = 66

super saver....6 cereals

y = 9(6)

y = 54

66 - 54 = 12.....so Luke saves $12 per month by buying the super saver brand."
