A plumber charges $65 to make a house call plus an additional charge of $42 per hour for labor. Write an equation to represent the total cost (y) for any number of hours (x).

the required equation to represent the total cost with respect to every hour will be

=》y = 42x + 65

Step-by-step explanation:

total cost (y) = charge to make a house call + additional charge for every our

so, total additional charge for x hours

= 42 × x = 42x

hence y = 65 + 42x ( where 65 is charge to make a house call , y is total cost and 42x is additional charge for x hours )
