A safety enterprise invoices its 30,800 prospects on the primary day of every month, with every of the 2 computer systems doing half the job. One invoicing machine produces on the charge of seven,700 per hour, and the opposite on the charge of 6,800 per hour.
“every of the 2 computer systems doing half the job”, subsequently every of the 2 computer systems produces an equal variety of invoices.
so.. 30,800/2 = 15,400 invoices
They simply differ on the variety of hours to complete.
7700x = 15400
x = 2 hrs. <— 1st laptop
6800y = 15400
y = 2.2647 hrs. <— 2nd laptop
That is how i perceive the issue =(
