Osvaldo has a goal of getting at least 30% of his grams of carbohydrates each day from whole grains today he ate 220 grams of carbohydrates and 55 were from whole grains did all the vowels go meet his goal why

Step-by-step explanation:

Given:

Total gram of carbohydrate consumed = 220 g

Mass of whole grain = 55 g

Expected mass % of carbohydrate from whole grain = 30%

Mass % = mass of carbohydrate from whole grain/total mass of carbohydrate consumed × 100

= 55/220 × 100

= 25%

Osvaldo did not meet his go because he consumed just 25% of his carbohydrate from whole grain.
