How can you tell the difference between additive comparison and multiplication comparison

In an additive comparison, we find the relation between two amounts by asking or telling how much more is one compared to the other.

In multiplicative comparison, there two different sets being compared. The first set contains a certain numbers of items. The second set contains multiple copies of the first set. Any two factors and their product can be read as a comparison.

step-by-step explanation:

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
