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 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.

Part A: If Yani's old cereal preference was $10, and the equation shows that the new cereal preference is $7, if I subtract the amount of the new one from the old, I'll get a total of $3.

Part B: For the old cereal preference, I have to multiply the cost of the cereal by the amount of times Yani buys it per month. So, 10(5) = $50. And the same with the new cereal preference 7(5) = $35. Now I have to subtract the amount of the new from the old once again. Yani will save $15 a month.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
