A restaurant uses a 15 pound bag of flour in 4 days. Each day, the bag of flour gets lighter as more flour is used. How much does the average amount of flour in the bag change each day? (Round to the nearest hundredth.)
The average amount of flour in the bag changes by 15 pounds in 4 days. Therefore, the average amount of flour in the bag changes by 15/4 = <<15/4=3.75>>3.75 pounds each day. Answer: \boxed{3.75}.
To find the average amount of flour the bag loses each day, we need to divide the total amount of flour lost by the number of days.
First, we need to determine the total amount of flour lost in 4 days. Since the bag weighs 15 pounds and is used up completely in 4 days, the total amount of flour lost is 15 pounds.
Next, we divide the total amount of flour lost by the number of days to find the average amount of flour lost each day.
15 pounds รท 4 days = 3.75 pounds
Therefore, the average amount of flour in the bag changes by approximately 3.75 pounds each day. (Rounded to the nearest hundredth)
To find out how much the average amount of flour in the bag changes each day, you need to calculate the rate of change or the average decrease in the amount of flour.
First, determine how much flour is used each day. Divide the total amount of flour used in 4 days (15 pounds) by the number of days (4 days):
15 pounds / 4 days = 3.75 pounds per day
Therefore, the restaurant uses 3.75 pounds of flour each day.
Next, calculate the average change in the amount of flour in the bag each day. Since the bag starts at 15 pounds and ends at 0 pounds over 4 days, the change in the amount of flour can be calculated by subtracting the initial amount from the final amount:
Change in flour = Final amount - Initial amount
Change in flour = 0 pounds - 15 pounds = -15 pounds
To find the average change, divide the change in flour by the number of days:
Average change in flour = Change in flour / Number of days
Average change in flour = -15 pounds / 4 days = -3.75 pounds per day
The average amount of flour in the bag decreases by approximately 3.75 pounds each day.
