One serving of granola provides 4% of the protein you need daily. You must get the remaining 48 grams from other sources. How ma
Inessa [10]
X=grams of protein you need daily.
Remember (4%=4/100=0.04).

x=4% of x + 48 g

therefore, we can suggest this equation:
x=0.04x+ 48
x-0.04x=48
0.96x=48
x=48/0.96
x=50

Answer: 50 grams of proteins you need daily.

Other method:
the remaning is equal to =100%-4%=96%

Therefore: 96% of x=48
Remember (96%=96/100=0.96)

we can suggest this equation too.
0.96x=48
x=48/0.96
x=50

Answer:50 grams of proteins you need daily.
