Let the original cost of the souvenir =S

You sold it at a profit of 15% =1.15S

Then it was resold at 60% profit + $25 for expenses. So, you have:

(1.15S)*1.60 + $25 =$300, solve for S

1.84S + $25 =$300 Subtract $25 from both sides:

1.84S =$300 - $25

1.84S =$275 Divide both sides by 1.84

S= $275/1.84 =**$149.45 - The original cost of the souvenir.**
