Sophia buys a certain brand of cereal that costs $5 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 = 4.35x

part a: how many more dollars is the price of a box sophia'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 she save each month with the change in cereal brand if he buys 5 cereal boxes each month? show your work. (10 points)

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
