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/shiftb. it has increased by 20 percentc. it has increased by 37.5 sets/hrd. it has decreased by 8.3 percente. it has decreased by 9.1 percent.

Production has increased 20/day

Step-by-step explanation:

In the first scenario production is 500/day and productivity 25 set/hour. After the changes, production is 600/day and 25 set/hour.

So productivity remains the same, nevertheless, as there are more productive hours per day, production raises, in this case the can be calculated as (New Production-Old Production)/Old Production=(600-500)/500=100/500=0.2=20%.

As productivity remains the same, you do not ge more sets/shift, as shifts are shorter (8 instead of hours, so you get 200/shift instead of 250/shift). The rest of the option is false as productivity remains constant
