Question

The Dulac Box plant produces 500 cypress packing boxes in two-10 hour shifts. Due to higher demand, Dulac has decided to operate three eight-hour shifts instead. Dulac is now able to produce 600 boxes per day. What has happened to production:

a. It has increased by 50 sets/shift
b. It has increased by 20 percent
c. It has increased by 37.5 sets/hr
d. It has decreased by 8.3 percent
e. It has decreased by 9.1 percent.

Answer 1

b. It has increased by 20 percent

Explanation:

The Dulac Box plant produces 500 cypress packing boxes in two-10 hour shifts.

Means the plant produces 250 boxes in each 10 hour shift.

And per hour it produces:
`(250)/(10)=25` boxes

Due to higher demand, Dulac has decided to operate three eight-hour shifts instead. Dulac is now able to produce 600 boxes per day.

Means the plant produces 200 boxes in each 8 hour shift.

And per hour now it produces:
`(200)/(8)=25` boxes

Production rate is =
`(600-500)/(500)*100=20`%

Hence, the answer is : b. It has increased by 20 percent
