Aplumber charges $52.50 per hour plus a $75.00 service charge your father's firm hires him to fix some leaky pipes find the total charges if it takes the plumber 4.5 hours to complete the task

(4.5 x 52.5) + 75 = 311.25

The answer I got was $311.25. First set up the equation for the problem: $52.50(x) + $75 = total charges. Since "x" represents the number of hours, substitute "x" with 4.5. After completing the calculations, you should get $311.25. Hope this helped :))

in simplified version   it would be x ≤-4
