Answer:

(3600-4400)/4400*100%

=-18.18%=-18%

Answer 2

Answer : The percent decrease in number of calories consumed is, 18.18 %

Step-by-step explanation :

As we are given that:

Calories consumed by a body builder in yesterday = 4400 calories

Calories consumed by a body builder in today = 3600 calories

Now we have to determine the percent decrease in number of calories consumed.

$\text{Percent decrease}=\frac{\text{Calories consumed in yesterday}-\text{Calories consumed in today}}{\text{Calories consumed in yesterday}}\times 100$

Now put all the given values in this formula, we get:

$\text{Percent decrease}=\frac{(4400-3600)cal}{4400cal}\times 100$

$\text{Percent decrease}=\frac{800cal}{4400cal}\times 100$

$\text{Percent decrease}=18.18\%$

Therefore, the percent decrease in number of calories consumed is, 18.18 %
