Question

An electrician charges $50 for a service call plus $25 an hour. The last service call cost $125. If n= hours worked, write an equation to describe this situation.

Answer 1

125=50+25n

Explanation:

• to figure how many hours worked you want to subtract 50 from both sides
  `(125)/(-50)=(50+25n)/(-50)`
• you get 75=25n
• then you want to divide 25 from both sides
  `(75)/(/25) =(25n)/(/25)`
• then you get3=n
