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.

because 7x we know that the cereal box super saving brand is $7

10-7 = $3 is the difference in dollars between the two.

5*10= $50 the original brand

7*5= $35 with the super saving brand

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

it alot will look like this 4.4

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
