My question is: Benjamin went to McDonald's to buy something for dinner. 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? Your thoughts:
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. The final answer: 5.
