新东方补充材料上的102题,第二句根本看不懂,请指教
On a purchase of $120, a store offered a payment plan consisting of a $20 down payment and 12 monthly payments of $10 each. What percent of the puchase price, to the nearest tenth of a percent, did the customer pay in interest by using this plan?

这个downpayment的概念经常出现,那位给解释一下吧?谢谢!!
如果downpayment是定金的意思,那么是需要返还的吗?我想应该是首付吧
这题答案是20/120?
不好意思,刚刚才看到楼上的楼上也说到首付的意思了
应该就是 20/120 吧还请原作者告诉答案
谢谢,down payment如四楼所说是首期付款,答案正是16.7%
可我就是不明白,题中并未提到利息,这里突然冒出来,20怎么由首期付款变成了利息?
