Phil collects virtual gold in an online computer game and then sells the virtual gold for real dollars. After playing 10 hours a day for 6 days, he collected 540,000 gold pieces. If he immediately sold this virtual gold at a rate of $1 per 1,000 gold pieces, what were his average earnings per hour, in real dollars?
(A) $5
(B) $6
(C) $7
(D) $8
(E) $9
Here,
Total Hours he spent = 10hr * 6days = 60 hours
Total Earning real dollars in 60 hours = \(54* 10^4\)
But 1000 virtual coin = $1
therefore \(54* 10^4\) virtual coins= \(54* 10^4\) * \(\frac{1}{1000}\)= $540 real coin
Therefore in 60 Hrs he earns = $540 real gold coin
so in 1 hour he earns = \(\frac{540}{60}\) = $9
