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
hope it was helpful!
This is important because if you were to answer in complex fractions instead of its simplest form, you would have a tough time multiplying complex fractions together. You would get a HUGE denominator or numerator, which makes things difficult. It is important to write a fraction in its simplest form because of exactly that; making things simple. Would you rather multiply 64/132*64/132 or 1/2*1/2?
3/2x-7 Would be the equation
