Homework Answers
Solutions:
1. Average number of prescriptions
Step 1:
Calculate the total number of technicians and prescriptions
12 X 100 = 1200
20 X 125 = 2500
23 X 150 = 3450
8 X 175 = 1400
Average no.of prescriptions = Total no.of prescriptions / Total no.of technicians
= 1200 +2500 + 3450 +1400 / 12 + 20 +23 +8
= 8550 / 63
= 135.7
Average no.of prescriptions = 136
The avaerage number of prescriptions that can be filled by pharmacy technician daily is 136.
2. Percentage of alcohol
Step 1:
2 litres contain 20%
Which means 20% of alcohol in 2000mL
Amount of alcohol = 20 / 100 X 2000
Amount of alcohol = 400mL
400mL of alcohol in 2000mL.
Total mixture = 400 + 2000 = 2400mL
Percentage of alcohol mixture = 400 / 2400 X 100
Percentage of alcohol mixture = 16.66%
Step 2:
1 litre of 50% alcohol.
which means 50% of alcohol present in 1000mL
= 50 / 100 X 1000
Amount of alcohol = 500mL
Total mixture = 500 + 1000 = 1500mL
Percent of alcohol = 500 / 1500 X 100
Percent of alcohol = 33.33%
Step 3:
750mL of 80% alcohol.
80% of alcohol present in 750mL/
Amount of alcohol = 80 / 100 X 750
Amount of alcohol = 600mL.
Total mixture = 600 + 750 = 1350
Percent of alcohol = 600 / 1350 X 100
Percent of alcohol = 44.44%
