Quizplus · Accepted Answer

To calculate productivity, we need to determine the number of cakes produced per hour per baker.

In 2011, the bakers produced 200 cakes per day, so each baker produced 40 cakes per day (since there are five bakers).

Therefore, the productivity of each baker was:

40 cakes / 8 hours = 5 cakes per hour

In 2012, the bakers produced 249 cakes per day, so each baker produced approximately 41.5 cakes per day (since there are six bakers).

Therefore, the productivity of each baker was:

41.5 cakes / 8 hours = 5.19 cakes per hour

To determine the increase in productivity, we calculate the percentage increase from 5 cakes per hour to 5.19 cakes per hour:

(5.19 cakes per hour - 5 cakes per hour) / 5 cakes per hour x 100% = 3.75%

Therefore, the bakery's productivity increased by 3.75%.
