So slope intercept form is y=mx+b
m=slope b=y intercept
convert current equation to slpe intercept
y-4=x-8
add 4 to both sides
y=x-4

Define their percentage:
----------------------------------
Adam = 100%
Tapiwa = 100 + 5 = 105%
----------------------------------
Find their total percentage:
----------------------------------
100 + 105 = 205
----------------------------------
Find 1%
----------------------------------
205% = 697 liters
1% = 3.4 liters
----------------------------------
Find 100% (Adam):
----------------------------------
100% = 3.4 x 100
100% = 340 liters
----------------------------------
Find 105% (Tapiwa):
----------------------------------
105% = 3.4 x 105
105% = 357 liters
--------------------------------------------------------------------
Answer: Tapiwa = 357 liters and Adam = 340 liters.

Answer:
Story 2 because it is talking about how much they spend. ANOTHER HINT: That equation has all the numbers in story 2. They key is to look at how the problem is set up.
2x+3=3x-4
try to isolate the x term
you must do the same thing to both sides or else it won't be equal anymore
2x+3=3x-4
add 4 to both sides
2x+3+4=3x+4-4
2x+7=3x+0
subtract 2x from both sides
2x-2x+7=3x-2x
0+7=x
7=x
the answer is x=7
