Question 828445

Hi. I'm helping my 7th grader with homework. I haven't done pre algebra in ages. I need to solve a problem by: writing an inequality to represent each situation. Use x for the variable. Then solve the inequality, interpreting your solution in the context of the problem. So here we go. A fee of 12.50 is deducted each month from aubryns bank account. She currently has a balance of 75.00 in her account. She must maintain a balance greater than $0. Assume no deposits or withdrawals.
<pre>
Let amount of months the balance of $75 will last be x, and amount after x months, A(x).
Inequality: {{{highlight_green(A(x) = 75 - 12.5x)}}}.
Solving this inequality results in x being 6. This means that the $75 balance will only last 6 months 
before the account "runs dry."
You can do the check!!
