Billy and maria ordered flyers to advertise the school dance. flyers cost $8.75 for the
first 50, and $1.50 for each additional 10. the bill was $19.25. how many flyers did
they order?

120

because they got 50 for 8.75 and if you add 1.50 until you get to 19.25 you would get 120

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
