conversations.value: I would love to understand how to solve this problem: A vendor bought apples at 2 for $3 and plans to sell them at 5 for $10. He also bought 3 oranges for $2.70 and plans to sell them at $1 each. How much is his profit if he sells 5 apples and 5 oranges?
  Can you explain?

conversations.value: A vendor bought each apple for $3/2 = $1.50.
  He will sell each apple at $10/5 = $2 each.
  His profit for each apple is $2 - $1.50 = $0.50.
  His total profit for 5 apples is $0.50 x 5 = $2.50.
  He bought each orange for $2.70/3 = $0.90.
  His profit for each orange is $1 - $0.90 = $0.10.
  His total profit for 5 oranges is $0.10 x 5 = $0.50.
  Therefore, his total profit for selling 5 apples and 5 oranges is $2.50 + $0.50= $3.
