Number of ounces left is 1120
Step-by-step explanation:
- Step 1: Find number of ounces left after each day.
Given total soup prepared each day = 15 gallons
Amount served each day = 1/4 of 15 = 15/4 gallons
Amount left after each day = 15 - 15/4 = 60 - 15/4 = 35/4 gallons
- Step 2: Convert gallons into ounces. 1 gallon = 128 ounces
35/4 gallons = 35/4 × 128 = 1120 ounces
