Equation:
since its a 15% increase its:
100+15=115
115/100=1.15 (changing from percentage to decimal)
1.15x=$10,120
x=$10,120/1.15
x = $8,800
the next given is a 10% increase so we do the same thing: 100+10=110
110/100=1.10 (changing from percentage to decimal)
1.10y=$8,800
y=$8,000
So the answer for how much it was raised 2 years ago is:
$8,000

Answer:
T = S + 12DStep-by-step explanation:
from y=mx+b:
T is total so it acts as "y"
S is the amount you start with so it acts as "b"
D is the increase per week so it acts as "m"
M=slope
b=y-intercept
y and x are coordinates
hope this helps, that is a much as I can give you with this little of information
