Alright, lets get started.
Suppose total values of drug Alejandro sold = x
He earns a 12% commission of the total sales of the statins that he sells to hospitals.
It means he get 12 % of commission of his total sale x.
So, the commission he get [tex] = x * 12 [/tex]
commission he get [tex] = x * \frac{12}{100} [/tex]
commission he get [tex] = 0.12 x [/tex]
As per given in question, he earned $60,000 in commission.
[tex] 0.12 x = 60000 [/tex]
Dividing both sides with 0.12
[tex] \frac{0.12x}{0.12}= \frac{60000}{0.12} [/tex]
[tex] x = 500000 [/tex]
It means his total sales is $ 500000. : Answer
Hope it will help :)
