Wages A mechanic's pay is \( \$ 14 \) per hour for regular time and time-and-a-half for overtime. The weekly wage function is
\( W ( h ) = \left\{ \begin{array} { l l } { 14 h , } \\ { 21 ( h - 40 ) + 560 , h > 40 } \end{array} \right. \)
where \( h \) is the number of hours worked in a week.
(a) Evaluate \( W ( 30 ) , W ( 40 ) , W ( 45 ) \) , and \( W ( 50 ) . \)
(b) The company decreases the regular work week to \( 36 \) hours. What is the new weekly wage function?
(c) The company increases the mechanic's pay to \( \$ 16 \) per hour. What is the new weekly wage function? Use a regular work week of \( 40 \) hours.
