Ahhh a factory worker in cambodia makes 320,000 cambodian riels per month. if 1 u. s. dollar equals 4000 cambodian riels, how much does the factory worker make in u. s. in dollars per year [show your work]

 For this case we must first take the amount $ per month. We have then: 1 $ ---> 4000 x = > 320000 Solving for x we ​​have x = (320000/4000) * (1) = $ 80 / month We have then that 1 year two 12 months ($ 80 / month) * (12 months / 1 year) = $ 960 / year Answer the factory worker make 960 U.S. in dollars per year
