At the beginning of last month, a stationery store had in stock 250 writing pads, which had cost the store $0,75 each. During the same month, the store made only one purchase of writing pads. What was the total amount spent by the store on the writing pads it had in stock at the end of last month? 1) Last month the store purchased 150 writing pads for$ 0,80 each.

2) Last month the total revenue from the sale of writing pads was $180. The OA is E. Why 1) is not sufficient?

Tnx

that's a poorly phrased question at best. I'd guessed A too if I didn't see the OA. I guess the reasoning is that the store could've sold some writing pads which changed the number of leftover at the end of the month.
