A school choir needs to make T-shirts for its 75 members and has set aside some money in their budget to pay for them. The members of the
choir decided to order from a printing company that charges $3 per shirt,
plus a $50 fee for each color to be printed on the shirts. Which equation
represents the relationship between the number of T-shirts ordered, the
number of colors on the shirts, and the total cost of the order. *
A) D = 3T + 50C
B) D = 3(75) + 50C
C) D=3(75) + 50
D) D=3(75)

hi! i think the answer is 1/2 : )

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
