Answer:
It would costs US$ 3,044.5 to purchase a hard drive priced at HK$ 390.
Step-by-step explanation:
We have that
[tex]\frac{US}{HK} = 0.1281[/tex]
This means that 1 US dollars is worth 0.1281 HK dollars.
How many US dollars will it cost to purchase a hard drive priced at HK$ 390?
This can be solved by a simple rule of three.
1US$ - 0.1281 HK$
x US$ - 390 HK$
[tex]0.1281x = 390[/tex]
[tex]x = \frac{390}{0.1281}[/tex]
[tex]x = 3,044.5[/tex]
It would costs US$ 3,044.5 to purchase a hard drive priced at HK$ 390.
