【紧急求助】prep的DS题~~~

During a one-day sale, a store sold each sweater of a certain type for $30 more than the store's cost to purchase each sweater. How many of these sweaters were sold during the sale?

1. During the sale, the total revenue from the sweater of these sweaters was $270.

2. During the Sale, the store sold each of these sweaters at a price that was 50% greater than the store's cost to purchase each sweater.



这道题，不是说每件毛衣比成本高30刀吗？而revenue就是270.不是直接270除以30=9件吗？
