We know that
• Shroud made $80,000.
,• He received $23,000 in donations.
,• Shroud makes $3 per subscriber.
First, we need to know the total amount of money Shroud made only with subscriptions.
[tex]80,000-23,000=57,000[/tex]Now, if he does $3 per sub, we just need to divide
[tex]\frac{57,000}{3}=19,000[/tex]
