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.
![80,000-23,000=57,000](https://img.qammunity.org/2023/formulas/mathematics/college/kt47ive2435b6phjbagz2z5vzpi2ejsuxt.png)
Now, if he does $3 per sub, we just need to divide
![(57,000)/(3)=19,000](https://img.qammunity.org/2023/formulas/mathematics/college/1t1cxh42z54husx3ofwif4i5vnq17g321w.png)
Therefore, shroud had 19,000 subscribers last month.
