He bought a salad, a burger, and two packs of fries. He paid in total $15. How much did the burger cost, if one pack of fries was for $2 and the salad was three times that price?
Answer: 
Benjamin paid for the fries 2 * 2 = $4.
The salad was three times the price of one pack of fries, so it cost 3 * 2 = $6.
The cost of the burger was 15 - 6 - 4 = $5.
