A pasta recipe for 3 servings uses 90 grams of cheese and 150 grams of pasta. A larger batch uses 330 grams of cheese with both ingredients scaled equally. How many grams of pasta does it use? Enter the number of grams.

Explicación

The cheese has been multiplied by 330 divided by 90, or eleven thirds, so the pasta must be 150 times eleven thirds, which is 550 grams. Adding the 240-gram cheese increase to the pasta would give 390 grams and would apply an additive change instead of the shared factor.
