Answer:
a). 219=S+18 h.... equation, where S is the one time fee, and h is the number of hours of service
b). The one time fee for the trash dumpster=$75
Step-by-step explanation:
The expression for the total charges for debris removal can be written as;
T=S+Rh
where;
T=total charges
S=standing one time fee
R=charges per hour
h=number of hours of service
In our case;
T=$219
S=unknown
R=$18
h=8 hours
replacing;
219=S+(18×h)
219=S+18 h.... equation
219=S+144.... equation
S=219-144=75
The linear equation for the amount earned is;
219=S+18 h
The one time fee for the trash dumpster=$75
