Answer:
600
Explanation:
We have to find the number of calories that 6 pounds is.
1 pound = 3500 calories
6 pounds = 6 * 3500 = 21000 calories
In 5 weeks we have 35 days. Let us divide 21000 by 35 to find how many calories that is per day:
21000 / 35 = 600
The number of calories must therefore be decreased by 600 every day.
