Inequality: 97 + .10x < 113 Solve for x

OpenStudy (yttrium):

Do you have an answer?

OpenStudy (anonymous):

i dont know how to solve this :(

OpenStudy (anonymous):

this was the question "Joanne has a cell phone plan that charges a flat rate of $97 and $0.10 for every text she sends. Her goal is to spend less than $113 on her phone bill each month. Which of the following describes the number of texts she sends?" so i put it into this inequality.

OpenStudy (anonymous):

and here are the answer choices so i dont get it!

OpenStudy (anonymous):

a. at least 160 b. no more than 160 c. fewer than 160 d. more than 160

OpenStudy (yttrium):

Just follow the law of axioms (transpositions)

OpenStudy (anonymous):

I think C is correct :)

OpenStudy (yttrium):

\[97+.10x < 113\] is your eq'n, right? What you need to do is to combine similar terms. Therefore, .10x <113 - 97 Can you do the next steps?
