Question

lawana has a leaky pipe in her home, so she hired a plumber that charged a flat fee of $65 to make a house call, plus $35 per hour. how many hours did plumber work if alices repair cost totaled $345

Answer 1

Let h=number of hours worked
let c=total cost

so 35 per hour can be 35h, plus the flat fee of 65=the total cost

c=35h+65

so now plug in 345 for c and solve for h

345=35h+65

Answer 2

Thank You so Much!!!
