Solutions

Chapter 2.1, Problem 67E
To determine

To find the tax, taking 8 % of the purchase price we can write.

  T(x)=8x100,    x>0  T(x)=0.08x

The required algebraic function is T(x)=0.08x

Expert Solution

Answer to Problem 67E

The required table as shown below:

  xT(x)=0.08x20.08(2)=0.1640.08(4)=0.3260.08(6)=0.4880.08(8)=0.64

Explanation of Solution

Given information:

Find the different numeric values of T(x) for values of x

Plug the value x=2 in the function T(x)=0.08x then we get the value of T(2).

  T(2)=0.08(2)        =0.16T(4)=0.08(4)        =0.32T(6)=0.08(6)        =0.48T(8)=0.08(8)        =0.64

Hence, the required table as shown below:

  xT(x)=0.08x20.08(2)=0.1640.08(4)=0.3260.08(6)=0.4880.08(8)=0.64
