Write the piecewise function for the cost per unit for production of units in the wichita factory. that is, state the function c(x), where x is the number of units produced.

The piece-wise function for the cost per unit for production of units in the Wichita factory is:

       C(x)=   1    when   0≤x≤25000

          and  0.8  when    25000<x≤35000

The graph of C(x) is a straight horizontal line taking the constant value 1 in the interval [0,25000]

and a straight horizontal line taking the constant value 0.8 in the interval (25000,35000]

Hence, the piece-wise function C(x) is defined by:

       C(x)=   1    when   0≤x≤25000

          and  0.8  when    25000<x≤35000

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.
