Question

a nutrition label states that there are 36g of carbohydrates in each serving. this accounts for 12% of the daily value. how many grams of carbohydrates are recommended per day?

Explanation:

Step1: Set up proportion

Let $x$ be the recommended daily amount of carbohydrates. We know that 36g is 12% of $x$, so the proportion is $\frac{36}{x}=\frac{12}{100}$.

Step2: Cross - multiply

$12x = 36\times100$.

Step3: Solve for $x$

$x=\frac{36\times100}{12}=300$.

Answer:

300
