Step-by-step explanation:

This problem expects us to model the equation for the total cost of the services of the plumber given the conditions stated.

Say the fixed amount charged for coming to your house is $10

say the fix amount charged per is $3

and the time spent to do the job is X

Hence the scenario can be modeled as

$Y= 3x+10$

the equation is similar to the equation of a straight line

$Y= mx+c$
