A pharmacist found at the end of the day she had 4/3 as many prescriptions for antibiotics as tranquilizers. She had 28 prescriptions altogether. How many did she have for tranquilizers?
------------
She had 4x prescriptions for antibiotics to every 3x prescriptions of
tranquilizers.
-----
Equation:
4x + 3x = 28
7x = 28
x = 4
------
# antibiotic = 4x = 4*4 = 16 prescriptions
----
# of tranquilizer prescrips = 3x = 3*4 = 12
