Answer 2

`\huge\text{Hey there!}`

`\text{Your given information we know so far is:}\\\textsf{The subscription feeds that Kiersten received for ONE month by each of her}\\\textsf{subscribers was \boxed{\mathsf{\$10}}. She has a total of \boxed{\mathsf{100}} people since last month, that means }\\\textsf{Kiersten should most likely be earning}\rightarrow\boxed{\mathsf{1,000}}\mathsf{\ (because \ 100* 10 = \$1,000).}\\\\\text{Reading further more:}\\\textsf{Your new month has approximately 30 new subscribers that has joined Kiersten}`

`\textsf{site, and about 10 subscribers got rid of their subscription. This let us}\\\textsf{us know that subscription \underline{increased} by about \boxed{\mathsf{20}} subscriptions (because }\\\mathsf{30 - 10 = 20)}\\\\\rm{120*10 = total \ earnings \ for\ Kiersten\ business}\\\rm{120*10 = \$1,200}\\\\\\\huge\text{Therefore, your answer is: } \boxed{\mathsf{\$1,200}}}\huge\checkmark`
