The other software package costs $60 and covers up to 10 devices. How much money, in dollars, can the school save by buying the $60 software package instead of the $40 software package? Let's think first. Chain of thought: <hau> Wata makaranta tana sayen manhajar kare ƙwayoyin cuta don rufe na'urori 50. Kunshin software guda ɗaya yana biyan $ 40 kuma yana rufe na'urori har 5. Sauran kunshin software yana biyan $ 60 kuma yana rufe na'urori 10. Nawa ne kudin, a cikin dala, makarantar za ta iya ajiyewa ta sayen kayan aikin software na $60 maimakon na $40?
