John has consumed 1,600 calories so far today. He has also burned off 400 calories at the gym. He would like to keep his daily calorie total to 1,800 calories per day. How many calories does he have left to consume for the day? Is 1,000 a viable solution to this problem?

600 calories

Step-by-step explanation:

John has consumed 1600 calories out of which he has burned off 400. So the total calories for the day so far are:

1600-400

=1200 calories

He has to keep the count of calories upto 1800 per day and the consumed calories so far are 1200

So he needs to burn:

= 1800 - 1200

= 600 calories

He has to consume 600 calories more ...

Hence 1000 is not a viable solution to the problem as the remaining count of calories that need to be consumed are 600 ...

No; 1,000 will cause him to exceed 1,800.

Step-by-step explanation:

Given,

The consumed calories = 1,600,

Burned calories = 400,

Thus, the remaining calories = 1600 - 400 = 1200

Since, 1,800 calories per day would be like to keep,

Also, 1200 < 1800

Hence, remaining calories is less than the required calories,

And, the calories left to consume for the day = Required calories - remaining calories

= 1800 - 1200

= 600

Therefore, 600 is the viable solution to this problem.

Note : If 1,000 a viable solution to this problem then the required calories will be more than 1800 or exceed 1800.
