Question 1120885
in 1994, the funding was x.
in 1995, the funding was x + .75 billion.
in 1996, the funding was x + .75 + .15 billion.


for the 3 years, the funding ws 9.48 billion dollars.


sum up all the funding for the 3 years and you get 3 * x + 2 * .75 + 1 * .15 = 3 * x + 1.65 billion.


3 * x + 1.65 = 9.48


subtract 1.65 from both sides of this equation to get 3 * x = 7.83.


solve for x to get x = 7.83 / 3 = 2.61 billion.


in 1994, the funding was 2.61 billion.
in 1995, the funding was 2.61 + .75 = 3.36 billion.
in 1996, the funding was 3.36 + .15 = 3.51 billion.


2.61 + 3.36 + 3.51 equals total funding of 9.48 billion.


solution checks out.


solution is:


2.61 billion in 1994.
3.36 billion in 1995.
3.51 billion in 1996.
