Not confusing at all, simply replace wherever you see an x with the given value,
C(x) = .75x + 5
C(0) = .75(0) + 5 = 5
that rules out a), b), and e)
C(50) = .75(50) + 5 = 42.5
so far, only c) works
simply check by finding C(100)
A certain economy's consumption function is given by the equation
C(x)=0.75x+5
where C(x) is the personal consumption expenditure in billions of dollars and x is the disposable personal income in billions of dollars. Find C(0), C(50), and C(100).
a. C(0)=42.5, C(50)=5, C(100)=80
b. C(0)=42.5, C(50)=80, C(100)=5
c. C(0)=5, C(50)=80, C(100)=80
d. C(0)=5, C(50)=42.5, C(100)=80
e. C(0)=80, C(50)=42.5, C(100)=5
This is so confusing.
Thanks for your help.
