Carpenter Charlie charges $15 per hour plus a flat rate of $100. Carpenter Chris charges $20 per hour plus a flat rate of $50. For how many hours of work will the total charge be equal? Let x equal the number of hours worked and let y equal total that the carpenter will charge

after 10 hours the charge will be equal

Step-by-step explanation:

15x+100 =y Charlie

20x+50 =y Chris

Just trial and error

if x=1 hour then

Charlie 15*1+100= $115

Chris 20*1+50=$70

if x=5 hours

Charlie 15*5+100=$175

Chris 20*5+50=$150

if x=10 hours

Charlie 15*10+100=$250

Chris 20*10+50=$250
