Question

GIVING Brainliest to the first right answer 1.Sam, an electronics technician, charges $145 for a
service call plus $55 per hour for each hour of service to
perform the repair. Using h for hours, write an equation for
the total amount, A, Sam would earn for each job.


2. How many hours must Sam work in order to earn $530?

Answer 1

$\color{cadetblue}Solution \: (1) :$

Base fee for a service call = $145

Fee charged per hour = $55

Let the number of hours be depicted by h .

This statement can be written in an equation as :-

$\color{hotpink} = 145 + 55h$

Therefore , an equation to find the total amount Sam would earn for each job = 145 + 55h .

$\color{cadetblue}Solution \: (2) :$

Number of hours Sam has to work in order to earn $530 :-

$= 145 + 55h = 530$

$= 55h = 530 - 145$

$= 55h = 385$

$= h = \frac{385}{55}$

$\color{olive} h \color{hotpink}= 7$

Which means Sam has to work for 7 hours to earn $530 .

Therefore , Sam has to work for 7 hours in order to earn $530 .
