Question:If a person needs to burn 3500 Calories to lose one pound, how would you write an equation that represents the number of Calories a person would have to burn a day to lose four pounds in 2 weeks...

I know what the answer is (1000 Cal./day), i just cant figure out how to write an equation for that with a variable...

Let w be the number of calories to burn to lose 1lb in 1 day, and W be the number to burn each day to lose 4lb in 2wk.

Then:
W = 4w / (2 * 7)
W = 2w / 7
W = 2 * 3500 / 7
W = 1000.

The person has to burn 1000 cal / day.
6th grade? How old is that? 10? I'm 15 and even I can't do that math!
You need to burn 3500 Calories per day to lose one pound.

You want to lose four pounds, so... you would need to burn 3500 Calories TIMES 4 = 14,000 Calories altogether.

2 weeks is the same as 14 days... because there are 7 days in a week.

So divide the 14,000 Calories by 14 days... and that will tell you how many Calories you need to burn PER DAY...

14,000 Calories / 14 days = 1,000 Calories / day...

# of Cals to burn per day = (3,500 Cal / 1 lb) x No. of Lb / # Days

DONT COPY ME
3500 cal = 1 pound then you need to lose 4 pounds over a 2 week course which is 14 days so.

4 pounds equal 3500 times 4 equals 14000

then 14000 divided by 14(days) equals 1000

so like you said 1000 cal./day to lose 4 pounds over 2 weeks.
You need to burn 3500 Calories per day to lose one pound.

You want to lose four pounds, so... you would need to burn 3500 Calories TIMES 4 = 14,000 Calories altogether.

2 weeks is the same as 14 days... because there are 7 days in a week.

So divide the 14,000 Calories by 14 days... and that will tell you how many Calories you need to burn PER DAY...

14,000 Calories / 14 days = 1,000 Calories / day...

# of Cals to burn per day = (3,500 Cal / 1 lb) x No. of Lb / Total No. of Days

That's how you get the 1000 Calories / day...

# of Calories .. (3,500 Calories / 1 LB)(4 LBS)
to burn per .. = ------------------------------...
day .... .... ...14 Days

# of Calories
to burn per .... = 1000 Calories / day
day
to lose 4 pounds, he has to burn 3500 times 4 calories, which is 3500(4)=14,000 calories. In 2 weeks (14 days) , he must lose 14000/14 = 1000 calories/day.
So, you want an equation.

3500/lb * 4 lb = 14000

So 14000 is what you are trying to reach.
14 days is the time limit.
So, 14 * (what value) = 14000.
If you let x = (what value), then you have the equation:

14x = 14000

or more accurately (i.e. including units):

14 days * x = 14000 cal.

solving this gives:

x = 14000 cal/14 days or 1000 cal/day
