Ihave to solve this question! 15 points here is a test for all of you a> if items a + b = $ 25 b> and items b + a + c = $46 c> and items b + b + b = $30 d> and item a = $ 15 what is item c ? find the answer by using only two of the lettered lines. ex: " you can find the answer by using lines a> and b> and doing this with them." said the unknown sranger typing an answer.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

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
