Answer 1

Answer: 30 ounces, 90 ounces

If the infant formula mixture required for the neonatal intensive care unit is 1/4 formula and 3/4 water, then the pharmacy technician must use ¼ of 120 ounces or 30 ounces of formula and 90 ounces of water.

Answer 2

Let:

x    be the amount formula (oz)

3x  be the amount of water (oz)

x  + 3x = 120

      4x = 120

        x = 30

Then:

x   = 30

3x = 90

A 120 oz of ready to consume infant feed should be composed of 30 oz of formula and 90 oz water.
