Step-by-step explanation:
a) Let negative means the turtle position when descending and positive for going up. Therefore since the turtle was 850 meters below see level, it was at -850. It then moves 165 meters up, hence its new position is -685 meters (-850 + 165). Lastly it moves down 165 meters, hence its new position is -850 meters (-685 - 165)
b) The change in position is the sum of the movements = +165 - 165 = 0 meters.

Answer:
$214
Step-by-step explanation:
selling price= $107,000
subtract 10%down payment
107,000- (107,000*.1)
107,000-107,00
96,300
Interest rate= 8%
Annual payment= 96,300* 0.08
$7704
per month payment= 7704/12
$624
payment on closing only for 10 days
642*(10/30)
$214
