I NEED HELP ASAP Luke usually goes to the store and buys a certain brand of cereal that costs $3.50 per box. Luke changes to shipping the order to his house instead of going to the store, the only issue is that he also pays $3.00 for shipping. The equation shows the price, y, as a function of the number of boxes, x, for the new brand.

y = 2.90x + 3.00

Part A: How much more 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. (2 points)

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. (3 points)
