My question is: Wilson goes to a fast-food restaurant. He buys 2 hamburgers for $5 each and 3 bottles of cola for $2 each. Wilson uses his $4 discount coupon. How much money does he pay in total? Your thoughts:
2 hamburgers cost 2 * 5 = $10. 3 bottles of cola cost 3 * 2 = $6. The total price without discount is 10 + 6 = $16. With the discount coupon, it's 16 - 4 = $12. The final answer: 12.
