Since we are already given the equation, we can already solve for the given problems above. Let us start with part 2 so we can easily answer part 1.
Part 2: the cost to get started before any books are printed. Using the equation, x = 0. So, y =1250+25(0)
y= 1250
So the cost to get started before any books are printed is 1250.
Now, to part 1, let us say, only 1 book is printed. So x=1
y = 1250 +25(1)
y= 1250 +25
y = 1275
So, for 1 book is 1275, and no book is 1250. This gives us the answer that the change in the total cost for each book printed would be $25. Hope this is the answer that you are looking for.

ABCD is quadrilateral
∠MBC+∠ABC=180°
∠ABC =
The sum of all angles of quadrilateral = 360°
( Subtract 112 from both sides)
(Simplify)
(Divide both sides by 21)
___
16) Find m∠v
The polygon has 6 sides
Sum of angles:- (6-2)=180= 720°
so,
( Subtract 321 from both sides)
(Simplify)
( Divide both sides by 21)
Therefore, m∠v=19

Answer:
Given :
A man buys a few number of books at RS 72 each and a few number of pens at RS 25 each .
To Find :
If he buys 11 articles and pays RS 510 altogether,find the number of each article bought by him .
Solution:
Total no. of article = 11
Let x be the no. of books bought for RS 72 each
So, No. of pens bought for RS 25 each = 11-x
Cost of x books = 72x
Cost (11-x) pens = 25(11-x)
He buys 11 articles and pays RS 510 altogether
So,72x+25(11-x)=510
72x+275-25x=510
47x=510-275
x=5
So,No. of pens bought for RS 25 each = 11-x=11-5=6
Hence 6 pens and 5 books were bought by him.
