In 1996, funding for a program increased by 0.15 billion dollars from the funding in 1995. In 1997, the increase was 1.39 billion dollars over the funding in 1996. For those three years the funding was 9.70 billion dollars. How much was funded in each of these three years?
Answer provided by our tutors
Let
x = the funding in 1995 in billions of dollars
x + 0.15 = the funding in 1996
x + 0.15 + 1.39 = the funding in 1997
For those three years the funding was 9.70 billion dollars:
x + x + 0.15 + x + 0.15 + 1.39 = 9.70

........
x = 2.67 billions of dollars was the funding for 1995
x + 0.15 = 2.67 + 0.15 = 2.82 billions of dollars was the funding for 1996
2.82 + 1.39 = 4.21 billion of dollars was the funding for 1997
