PLZ HELP Luke buys a certain brand of cereal that costs $11 per box. Luke 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 = 9x Part A: How many more dollars is the price of a box of Luke’s original brand of cereal than the price of a box of the super-saving brand? Show your work. Part B: How much money does Luke save each month with the change in cereal brand if he buys 6 cereal boxes each month? Show your work.

A: y = 11x witch is the function for the original boxes that he bought witch was $11 per box while on the other hand, it was $9 per box of cereal so Y = 9x is going to be the function for the super saving brand so, therefore, it is a $2 difference between the original and the super saving brand and since there are 6 bowls of serial able to be made so...

Original brand 

Y = 11(6)

Y = 66

Super saving brand 

Y = 9(6)

Y = 54

So therefor 66-54=12 

That means that Luke saves $12 per month.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
