Problema Solution
A tree removal service assesses a $400 fee and then charges $80 per hour for the time on an owner’s property
a) is $750 enough for 5 hours work?
b) graph the ordered pairs (hours, cost)
c) give the domain and range
Answer provided by our tutors
a linear equation for total cost, 'C', is:
C=80h + 400
where 'h' represents the hours worked at a rate of $80
for 5 hours of work, the total cost would be:
80*5 + 400 = 400+400 = 800
so $750 would not be enough to pay for 5 hours of work
to graph the equation, please visit doyourmath.com, quickmath.com or use the trial version of Algebrator (see the Function wizards for domain/range functions, entering "C(h)=800h+400" as the equation [functional notation is required in the Function wizards]):
