Average 80442

The daily need for fat for a person is 80g on average. Almonds contain 45% fat. How many grams of almonds would a person have to eat if he wanted to cover his daily need for fats by eating only almonds?

Correct answer:

x =  178 g

Step-by-step explanation:

$$\begin{gathered} a=80\text{g} \\ r=45\%=\frac{45}{100}=\frac{9}{20}=0.45 \\ r\cdot x=a \\ 0.45\cdot x=80 \\ 0.45x=80 \\ x=\frac{80}{0.45}=177.77777778 \\ x=\frac{1600}{9}\doteq 177.777778=178\text{g} \end{gathered}$$
