There are 16 oz in 1 lb.
So, 1 lb 4 oz = (1 * 16) + 4 = 20 oz
-- Each day, Robert feeds his dog 20 oz
If the bag is 40 lbs, and 1 lb = 16 oz
-- The bag is 640 oz
640 oz of food, divided by 20 oz servings
-- It will last 32 days.
To find out how long a 40-pound bag of dog food will last, we need to determine how many days' worth of food is in the bag.
First, let's convert 1 lb 4 oz to a standardized unit, such as pounds. There are 16 oz in one pound, so 1 lb 4 oz is equivalent to 1 + 4/16 = 1.25 pounds of dog food per day.
Now, we can calculate how many days' worth of food is in the 40-pound bag by dividing 40 pounds by 1.25 pounds per day:
40 pounds / 1.25 pounds per day = 32 days
Therefore, a 40-pound bag of dog food will last approximately 32 days.
