Answer:

After two hours the two plumbers will charge the same amount

Step-by-step explanation:

Set up your equations

Plumber 1:

y = 25x + 100

Plumber 2:

y = 50x + 50

Set the two equal to each other and solve

25x + 100 = 50x + 50

         -50              -50

25x + 50 = 50x

-25x           -25x

           50 = 25x

     50/25 = 25x/25  <- Divide both sides by 25

              x = 2

After two hours the two plumbers will charge the same amount
