Challenge 298 : A convenient sum and product?

A customer bought four items at a convenience store and they were charged £7.11 in total.

However, they also noticed that if the prices of the four items had been multiplied together instead of being added, the value would also have come to 7.11.

Given that one of the items was priced at £1.50, your task is to find the prices of the other three items.
