Answer:
$1200.
Step-by-step explanation:
We have been given that Kiersten runs a website that helps people learn programming. Every month, Kiersten receives a subscription fee of $10 from each of the subscribers to her website.
First of all we will find the number of subscribers for this month.
![\text{Total number of subscribers this month}=100+30-10](https://tex.z-dn.net/?f=%5Ctext%7BTotal%20number%20of%20subscribers%20this%20month%7D%3D100%2B30-10)
![\text{Total number of subscribers this month}=130-10=120](https://tex.z-dn.net/?f=%5Ctext%7BTotal%20number%20of%20subscribers%20this%20month%7D%3D130-10%3D120)
Now let us multiply number of total subscribers of this month by 10 to find the amount Kiersten will earn by her online business.
![\text{Kiersten's earnings this month from online business}=120*10](https://tex.z-dn.net/?f=%5Ctext%7BKiersten%27s%20earnings%20this%20month%20from%20online%20business%7D%3D120%2A10)
![\text{Kiersten's earnings this month from online business}=1200](https://tex.z-dn.net/?f=%5Ctext%7BKiersten%27s%20earnings%20this%20month%20from%20online%20business%7D%3D1200)
Therefore, Kiersten will earn $1200 this month by her online business.
