Question

A construction company charges $18 per hour for debris removal, plus a one time fee for the use of the trash dumpster. the total fee for eight hours of service was $219, right and solve a linear equation to find a one time fee for the trash dumpster.

Answer 1

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
