For this problem, let's assign a variable for the total amount of proteins needed daily/ Let that parameter be x. Now, the 48 grams is part of the total. The other portion is the one expressed in percentage. That accounts for 4% of x. Therefore, the equation would be:
x = 48 + 0.04x
Solving for x
x = 50
Thus, you will need 50 grams of protein daily.
