Answer:
550g
Step-by-step explanation:
total g in 1 kg is 1000
so 1000 - 550 =450
the little check with the dash on top
Plug g(x) in for every x in f(x) then substitute 4, you’ll get (f o g)(4) = 34
Sorry, I guess I was in a hurry. This is how I did it after carefully reading the problem.
9.54% times which mobile phone (the one we are looking for=y) would use 1.908
that is: 0.0954 times y=1.908
0.0954y=1.908 dividing each side by 0.0954, we get y=20
So, the answer is y=20, or the mobile phone is 20
