You work in a chemical lab. last quarter, you successfully completed an average of about 5 chemical analyses per day. this quarter, you have increased this average to about 8 per day. what is your percent increase? 12.5% 20% 37.5% 60% 62.5%

60%

Step-by-step explanation:

Since, According to the question,  Last quarter, we successfully completed an average of about 5 chemical analyses per day.

Therefore initially our average = 5 chemical analyses per day.

Again, From the question, This quarter, we have increased this average to about 8 per day.

Therefore New average =chemical analyses 8 per day

Thus, Percentage change in the average = (Initial average - New average)×100/ initial average  

=

=

= 60 %

Therefore, Percentage change in the average=60 %

60%

Step-by-step explanation:

Given : Last quarter, you successfully completed an average of about 5 chemical analyses per day.

This quarter, you have increased this average to about 8 per day.

i.e. Previous average = 5 per day

New Average = 8 per day

Increase in average = Previous - New

= 8-5 = 3 per day

Now, the percent increase =

Hence, Your percent increase = 60%
