Final answer:
The proration for the seller is $509.95.
Step-by-step explanation:
To calculate the proration for the seller, we need to determine the number of days between November 30th and June 2nd. November has 30 days. December has 31 days.
January, February, March, April, and May each have 31 days. So, the total number of days is:
30 + 31 + 31 + 30 + 31 + 2 = 155 days
Now, we divide the insurance charge of $1200 by 365 days to get the daily proration amount:
$1200 / 365 = $3.29 per day
Finally, we multiply the daily proration amount by the number of days to get the proration for the seller:
$3.29 * 155 = $509.95
