Hamish and Harry work as plumbers. Harry earns a dollar more than 5/4 the amount Hamish earns per hour. The amount Harry earns per hour is $2 less than 7/5 the amount Hamish earns per hour. How much does each of them earn per hour?
Harry earns $1+(5/4)•x and also (7/5)•x-$2 $1+(5/4)•x = (7/5)•x-$2 $1+$2= (7/5)•x-(5/4)•x 3=(7•4•x-5•5•x)/20 3=3x/20 3•20=3x X=20, Hamish earns $20 Substitute x in one of the expressions 1+(5/4)•20=1+25=26, Harry earns $26
