Question

Please help! @Astrophysics @DanJS

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.

Answer 1

For part A, we know that the new box is $9 per box, and his original was $11 per box, so subtract 11 - 9 to get the answer. So what is your answer for part A?
