= the total charged by Jones.
= the total charge by Phenso.
h = number of hours.
"Jones' charges $50 for a service call plus an additional $39 per hour for labor,"
"...and Phenso charges $32 for a service call plus an additional $45 per hour for labor."
If both companies were to charge the same, then
Solve for h. Subtract 32 from both sides.
Subtract 39h from both sides.
Finally, divide by 6.
If h=4, then:
Jones' electric would be the best (cheapest) choice at $206 for 4 hours.
