Answer:
She will need [tex]1.68kg[/tex]
Step-by-step explanation:
The recipe says she needs 480 grams for 4 people.
For 14 people, we can write the following equation :
[tex]\frac{4people}{480grams}=\frac{14people}{x}[/tex]
We can do this because there is a linear relationship between the grams of pasta she needs to cook and the amount of people that will eat.That linear relationship is in the recipe.
Finding the value of x :
[tex]x=\frac{(14people).(480grams)}{4people}=1680grams[/tex]
She will need 1680 grams. If we want the value in kilograms :
[tex](1680grams).(\frac{1kilogram}{1000grams})=1.68kg[/tex]
She will need [tex]1.68kg[/tex] of pasta
