Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
I get the answer you got for (1)
.90[1.1(.85[31])]
or, simply
.90 * 1.1 * .85 * 31
For (2), I got 38.9%
(89.99 - 54.99) / 89.99
For (3), I got Cost = 400, Markup = 200 (50%)
600 = 1.5x
x = 600/1.5
x = 400
check
400 + .50(400) = 600
OK
