Final answer:
To produce 1000 parts, Firm A would need to work between 8 and 9 hours.
Explanation:
To find the number of hours Firm A would have to work to produce 1000 parts, we can use the formula:
Total parts = Production rate * Hours worked
Given that Firm A produces 100 parts/hour and operates for 10 hours each day, we have:
Total parts = 100 parts/hour * 10 hours/day = 1000 parts/day
If the productivity were increased by 20%, the new production rate would be:
New production rate = 100 parts/hour + 20% * 100 parts/hour = 120 parts/hour
To find the new number of hours needed to produce 1000 parts, we can rearrange the formula:
New hours = Total parts / New production rate = 1000 parts / 120 parts/hour = 8.33 hours
Therefore, the plant would need to work between 8 and 9 hours to produce 1000 parts.
