Find the original price of a jacket if the sale price is $94.00 after a 20% discount A. $112.80
B.$ 117.50
C. $114.00
D. $188.00

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.

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

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

the answer would be  

a.

3: 1
