The revenue (money received before expenses, tax, etc.) a company makes from selling a particular item is calculated by multiplying the selling price by the number of items sold.
Last year Toys-were-Us sold 3 million computer games at a price of £50 each.
Toys-were-Us wish to maximise their revenue from sales of computer games this year.
However a change in price could lead to a change in the number of computer games sold.
Toys-were-Us expect there will be a change of 500 000 computer games sold for every £2 change they make in the price.
So for every £2 increase to the price, sales drop by 500 000.
For every £2 decrease in price, sales increase by 500 000.
