Answer by Theo(13342) (Show Source): You can put this solution on YOUR website! c = cost
m = markup
s = selling price
s = 80
c + m = 80
m = .33 * c
replace m with .33 * c to get:
c + .33 * c = 80
simplify to get:
1.33 * c = 80
solve for c to get:
c = 80 / 1.33 = 60.15037594 = 60.15 rounded to the nearest cent.
