Answer:
$550
Explanation:
The second option paying $100 for 14 months would cost you $1400 because 14 x 100 = 1400.
There's also the $150 down payment, meaning you actually pay $1550 after this has been added on top of the $1400 worth of monthly payments.
$1550 - $850 = $700, meaning you would save $700 by paying for the total amount at the time of the purchase rather than later.
