When a machine is in US dollar and a Japanese needs to pay in Yen, the amount should be converted into Yen.
A US Made machine cost $500
Exchange rate : 100 Yen = $1
In order to purchase the machine, a Japanese needs to pay:
= Cost of the machine in dollars × Yen per dollar
= $500 × 100
= 50,000 yen
Therefore, a machine of $500 will cost a Japanese in 50,000 Yen.
