Let n represent the number of hours Steve work daily under regular pay
Let m represent the number of hours Steve work under night shift
Let w represent the number of hours Steve work on weekends
a) Earning under regular pay can be described by
f(n) = $24.39n
b)
earning for working m hours night shift = (24.39 +0.58)m = $24.97m
Daily-earnings for working under night shift premium will be
f(m, n) = $(24.39n + 24.97m )
C) Earning under weekend premium can be described by
f(w) = (24.39 + 0.39)w
f(w) = $24.78
d)
Earnings for the night shift on Saturday can be described by
f(w) = (24.39 + 0.58 + 0.39)w
f(w) = $25.36w
e)
Earning for Saturday's Night can be described by
f(w) = 25.36w
He worked for 11 hours
