Contributions to the annual Grayson School fund raising campaign were 10% greater in 2004 that they were in 2003. In 2003, contributions were 15% greater than they were in 2002. If contributions for 2004 total $8855, what was the total in 2002? (remember to put your answer in dollars and cents)

Answer 1

contributions in 2002 ----
contributions in 2003 ---- 1.15x
contributions in 2004 ---- (1.1)(1.15x)

(1.1)(1.15x) = 8855

solve for x
