To finish an order in time the company had to produce 40 items daily, but it produced 20 items more daily and finished the order 3 days ahead of time. In how many days was the company supposed to finish the order?

Answer 1

d=# of days to finish the order

40d=60(d-3)

40d=60d-180

180=60d-40d

180=20d

d=180/20

d=9 days to complete the order
