Step-by-step explanation
To know how many more grams of servings does he need to hit his goal of 34g of protein we need to do a "rule of three"
1. Write all information provided
30 grams of serving size of protein powder = 25g of protein
x = 34g of protein
2. Cross multiply, and then divide
30grams of serving protein powder x 34g of protein = 1020
1020 / 25g of protein = 40,8 grams serving size of protein powder.
3. Subtract the regular serving size from the ideal serving size
40,8 grams of serving size of protein powder - 30 grams of serving size of protein powder = 10,8 grams of serving size of protein powder.
