<PRE><B>Question 1087846</B>
A pharmacist found at the end of the day she had
3/2 as many prescriptions for antibiotics as tranquilizers. She had 40 prescriptions altogether. How many did she have for? tranquilizers? 
:
a = antibiotics
t = tranquilizers
t = 3/2a
---------------------
a+t = 40
a+3/2a = 40
5/2a = 40
a = (40*2)/5
a = 80/5
a = 16
You figure out the tranquilizers (40-a)
