To determine Nick's hourly earnings for the job, we divide the total fee he charges by the number of hours worked. Since the problem does not provide the total fee, we cannot calculate Nick's hourly earnings.
The effect on their checking account balance would be -$10,200.
To determine the effect on their checking account balance, we need to calculate the total amount deducted over the course of the year. This can be done by multiplying the monthly amount deducted by the number of months in a year (12 months).
In this case, the Walkers deducted $850 each month. So, to find the total deduction for the year, we can multiply $850 by 12:
$850 * 12 = $10,200
Therefore, the effect on their checking account balance was a deduction of $10,200. The correct response is "$10,200."
