Answer: f(5) = 16
Step-by-step explanation:
f(n) = (2n + 3)2 – 2n
f(5) = ((2 x 5) + 3)2 – 2 x 5
f(5) = (10 + 3)2 – 10
f(5) = (13)2 – 10
f(5) = 26 – 10
f(5) = 16
Part A: Chose some value for x, that means any amount of books to print for example 100 books, so x=100
Replace x=100 in C(x) and solve:
C(100)=3.5*100+1200=1550
Part B: Replace C(x) by 1900 and solve for x from the given equation:
1900=3.5x+1200
3.5x=1900-1200
x=700/3.5= 200
Part C: the statement C(20)=1270 means that 1270 is the cost for printing 20 books.
Part E: C(40.5)=1341.75 I think this statement is incorrect given the context because x means number of books to print so this value must be an integer number.
