Question

Mr. Anderson’s doctor has advised him to goon a diet. He must reduce his caloric intake by 15%. He currently eats 2800 calories per day. Calculate his new daily caloric intake rate in two different ways, using two different multipliers.

Answer 1

Mr. Anderson eats per day = 2800 calories.

Doctor has advised him to reduce his caloric intake by 15%.

We have to find his total calories intake per day by using two different ways.

First method is, We will find 15% of 2800 calories.

15% of 2800 calories = $(2800)(\frac{15}{100})$

= $\frac{(2800)(15)}{100}$

= $\frac{42000}{100}$

= $420$ calories

Now Mr. Anderson's calories intake reduced by 420 calories.

So his daily caloric intake = $(2800 - 420)$ calories = 2380 calories.

Second method is,

Here given, calories intake reduced by 15%.

So, his caloric intake is $(100-15)$% = 85%.

Now we have to find 85% of 2800 calories.

85% of 2800 = $(2800)(\frac{85}{100})$

= $\frac{(2800)(85)}{100}$

= $\frac{238000}{100}$

= $2380$ calories

So we have got the required answer.

His daily caloric intake is 2380 calories.

Answer 2

2800 x 0.15 = 2380.
2800-15% = 2380
does that help. also 2380 is his new daily caloric intake
