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

Answer:

125=50+25n

Step-by-step explanation:

• to figure how many hours worked you want to subtract 50 from both sides $\frac{125}{-50}=\frac{50+25n}{-50}$
• you get 75=25n
• then you want to divide 25 from both sides$\frac{75}{/25} =\frac{25n}{/25}$
• then you get3=n
