Question

An auto mechanic charges (C) an initial fee of $50 and then $40 per hour. If (h) represents hours, how much will the mechanic charge if he works 10 hours in one day?

Answer 1

The charging rate equation for the auto mechanic is C = 50 + 40h(50 for the initial fee and 40 times h for every hour). If he works 10 hours in one day we have to plug in 10 into the hours spot, h.

C = 50 + 40(10)

Now we solve for C

C = 50 + 400

C = 450

The auto mechanic charges $450 for 10 hours.

Answer 2

The mechanic charge if he works 10 hours in one day will be $450.

What is the equation of line?

The equation of line is given as

y = mx + c

Where m is the slope and c is the y-intercept.

An auto mechanic charges (C) an initial fee of $50 and then $40 per hour.

y-intercept = 50

slope = 40

Then the equation of line will be

y = 40x + 50

Where, y is total charge and x be the number of hours.

The mechanic charge if he works 10 hours in one day will be

y = 40 × 10 + 50

y = 400 + 50

y = $450
