A UK manufacturer plans to make 2,400 commercial coffee machines. Each machine needs three pump valves. The supplier prices are:
| Supplier | Price per pump valve |
|---|---|
| UK supplier | £2.40 |
| Overseas supplier | £2.05 |
Calculate the total amount the manufacturer would save by buying all of the pump valves from the overseas supplier rather than the UK supplier. Show your working.
Explain one reason why the overseas supplier may be able to charge a lower price for each pump valve.
