17 pages MUST be in smaller type and this is why ::: 

Let x be the number of pages in smaller type. 
Let ( 21 - x) be the number of pages in larger type. 

Thus, 48,000 = x ( 2, 400) + 1,800 ( 21 - x) 
48,000 = 2,400x + 37,800 - 1,800x 
10,200 = 600x 
10,200 / 600 = 600x / 600 

17 = x

Step-by-step explanation:

Regression Equation has the firm of,

Y = aX + b

please refer to my attachment for a and b.

So prepare table with columns of Y, X sq(x),......

then work out a and b according.

Finally sub a and b into the equation Y = aX + b
