Loisa will pay a total of $40 x 4 = $<<40*4=160>>160 for the first 4 months.

She will pay a total of $35 x 4 = $<<35*4=140>>140 for the next four months.

And she will pay a total of $30 x 4 = $<<30*4=120>>120 for the last four months.

Thus, she will pay a total of $100 + $160 + $140 + $120 = $<<100+160+140+120=520>>520 for 12 months including the down payment.

Therefore, Loisa can save $520 - $450 = $<<520-450=70>>70 if she buys the tablet in cash.

Loisa wants to buy a tablet that costs $450 cash. Since she does not have enough money, the store offered her an installment plan for 12 months. 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?
