I am going to buy exotic fruits. Dragonfruit costs  x-4 dollars. Starfruit is five dollars less expensive than rambutan. Rambutan costs 2x dollars more than dragonfruit. How much does it cost to buy one rambutan, two starfruits, and three dragonfruits? Your answer will be an expression that depends on x.

D = x - 4

R = D + 2x

S = R - 5

 

R + 2S + 3D = D + 2x + 2(D + 2x - 5) + 3D   =  6D + 6x - 10 = ... can you finish from here?
