 <translate> Loisa will pay a total of $40 x 4 = $160 for the first 4 months. She will pay a total of $35 x 4 = $140 for the next four months. And she will pay a total of $30 x 4 = $120 for the last four months. Thus, she will pay a total of $100 + $160 + $140 + $120 = $520 for 12 months including the down payment. Therefore, Loisa can save $520 - $450 = $70 if she buys the tablet in cash.
