please anyone help me in this question please help ​

Answer 1

Step-by-step explanation:

Let there be x articles.

Then the production cost of each article =3+2x

Total production cost =x(3+2x)=90

3x + 2x* = 90

2x3+3x - 90 = 0

2x2+15x - 12x- 90 = 0

2x(x - 6)+15(x - 6) = 0

(2x+15)(x - 6) = 0

x = 6 , - 15 /2

Number cannot be negative.

So, number of articles =6 and the cost of each article =Rs.15 .
