Given: A computer manufacturer sells a PC to a retailer for 40 percent more than it cost to produce. A customer buys the computer for 25 percent more than the retailer paid for the computer.
Asked: The price the customer paid was what percent greater than the cost of producing the computer?
Retailer's price = 1.4 cost to produce
Customer's price = 1.25 * retailer's price = 1.25 * 1.4 * cost to produce = 1.75 * cost to produce
The price the customer paid was what percent greater than the cost of producing the computer = 1.75 - 1 = .75 = 75%
