Answer to Problem 1P

  $285$ grams

Explanation of Solution

Given:

If your daily value of carbohydrates is 300 grams, then how many grams is 95% of your daily value of carbohydrates?

Calculation:

It has been given that daily value of carbohydrates is 300 grams.

Hence, 95% of daily value of carbohydrates should be equal to $95\%\text{ of 300}$

In order to find $95\%\text{ of 300}$ , subtract 5 % of 300 from 100% of 300

The percent table for this reasoning is shown below.

$100\%\to 300$

$10\%\to 300÷10=30$

$5\%\to 30÷2=15$

$95\%\to 300-15=285$

Therefore, $285$ grams should be equal to $95\%$ of daily value of carbohydrates.
