    so how much is the fixed cost if we know that he charges $35/hour: $270-(6x$35)

    i think it would be somewhat like 35*6=?, then that number divided by 270

    good. So, , the fixed is 60 like you said, which one is the cost, c in the expression 270 =(6x$35)+$60?

    so in the expression above , 270 is the fixed cost, so for x hours of labour and $60 fixed cost, we shall always have cost = (cost per hour) x(number of hours) +Fixed cost

    and rate per hour is 35 right?, this is our m, remember m is the gradient in the equation y =mx+b, so our m is 35 in this case
