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
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? 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.
This is sometimes true I say this because if u substitute your answers that can be different or can be the same. for ex. x=6 y=6; 6-3 and 6-3 will be the same but if x= 10 and y=15; 10-3 and 15-3 would give you different answers
