She will pay $100 as a down payment and pay $40 for the first 4 months; then $35 for the next four months; then $30 for the last four months. How much will Loisa save if she will buy the tablet in cash instead of on installment? Let's think first. Chain of thought: <hau> Loisa tana son ta sayi kwamfutar hannu da ta kai dala 450.
