Answer:
Step-by-step explanation:
Let d be days of work by the team.
At first, a team of workers had to produce 54 parts daily:
d days × (54 parts)/day = 54d parts
Then exceeding the schedule by 6 parts per day, the team not only finished the assignment 1 day earlier, but also produced 18 extra parts:
(d-1) days × (54+6 parts)/day = 60d - 60 parts
60d-60 = 54d + 18
6d = 78
d = 13
So the answer is:
If the team is making 54 parts per day, the team works 13 days.
If the team is making 60 parts per day, the team works 12 days.
