- I have to write an equation that would represent the final cost of the machine. Thanks!

Call the list price p
Given: ++p+=+800+
I think the equation would be:
+%28+p+-+.2p%29%2A%28+1+-+.1+%29+%2A%28+1+%2B+.06+%29+%2B+40+
+p%2A.8%2A.9%2A1.06+%2B+40+
cost of machine = +.7632p+%2B+40+
Just plug in +p+=+800+ to solve
