solve for x for part B,C
i just need B amd C
as we know the answer of A is
50x +120 = 1620
here x is the number of days .
so what we will do here to find part C
we will just isolate x
it will be
50x = 1620 -120
50x = 1500
x = 1500/50
x = 30
So he will spend 30 days on trip .
For part B
what we will do
50x +120= 1620
taking -120 on both sides
50x + 120 -120 = 1620 - 120
50x = 1500
now divide both sides by 50, we get
this is your Part B
