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%

Answer: 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 dayThus, Percentage change in the average = (Initial average - New average)×100/ initial average  = [tex]\frac{8-5}{5} \times 100[/tex]= [tex]\frac{3}{5} \times 100[/tex]= 60 %Therefore, Percentage change in the average=60 %
