serious [3.7K]

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.

$\text{Total number of subscribers this month}=100+30-10$

$\text{Total number of subscribers this month}=130-10=120$

Now let us multiply number of total subscribers of this month by 10 to find the amount Kiersten will earn by her online business.

$\text{Kiersten's earnings this month from online business}=120*10$

$\text{Kiersten's earnings this month from online business}=1200$

Therefore, Kiersten will earn $1200 this month by her online business.
