Tina goes to the store to purchase some CDs and DVDs. CDs cost $15 and DVDs cost $18. Which of the following expressions gives the total amount of money, in dollars, Tina will pay for purchasing 2 of the CDs and D of the DVDs?
______15+D
______30+18D
______18+D+30
______D(18+15)
选项
答案
The first step is to calculate the total cost of the CDs: 2(15)=30. You are given that, in addition to the 2 CDs, Tina also purchases D of the DVDs, each of which costs $18. Therefore, her cost for the DVDs was 18D. Now simply add the terms together to get 30+18D.
