 <translate> There are 50 / 5 = 10 sets of 5 devices in the school. So the school will pay a total of $40 x 10 = $400 for the $40 software package. There are 50 / 10 = 5 sets of 10 devices in the school. So the school will pay a total of $60 x 5 = $300 for the $60 software package. Thus, the school can save $400 - $100 = $300 from buying the $60 software instead of the $40 software package.
