Final answer:
Jim would be away from home for approximately 23 days.
Step-by-step explanation:
To find out how many days Jim would be away from home, we need to multiply the number of days he spends away from home in a month by the number of months he does this for:
3 1/2 days x 6 1/2 months = (7/2) x (13/2) = 91/4 = 22.75 days
Since we can't have a fraction of a day, we round up the decimal to the nearest whole number. So, Jim would be away from home for approximately 23 days.
