susan is buying three different colors of tiles for her kicthen floor. she is buying 25 more red tiles than beige tiles , and three times as many navyblue tiles as beige titles. if susan buys 435 tiles altogher, how many tiles of each color does she buy?

R=B+25
NB=3B
R+B+NB=435
you can solve this a number of ways. Post your work, and I will check. 
bobpursley, I am confused to the equations that you have just posted. However, this is what I figured out but I'm not if it's correct.
((25+R)B)+3N=435
