The profit that the bookstore can earn can be calculated by the following formula:
Profits = sales-costs
The sales included the amount of old books purchased at the back cover price and the amount of old books sold at 25% cheaper than the back cover price.
Assuming that the price on the back cover is X, the cost of buying old books at a 40% discount is 04X. Then, the secondhand bookstore would sell the old books at a 0.75% discount from the back cover price, which meant that the sales would be 0.75x.
Therefore, the profit that the bookstore could earn was:
Profits = 075X-04X = 035X
Therefore, the bookstore could earn a profit of 0.35x.
