Using simple interest, it is found that her interest charge this month will be of $30.
<h3>Simple Interest</h3>Simple interest is used when there is a single compounding per time period.
The amount of interest after t years in is modeled by:
I(t) = Prt
In which:
- P is the initial amount.
- r is the interest rate, as a decimal.
In this problem, considering the time in years, the parameters are:
Hence:
Her interest charge this month will be of $30.

All values of x that satisfy 2x+2/x+7 >= 0 are represented as x >= -1
<h3>How to graph the inequality on a number line?</h3>The inequality expression is given as:
2x+2/x+7 >= 0
Multiply both sides by x + y
2x+2 >= 0
Subtract 2 from both sides
2x > -2
Divide both sides by 2
x >= -1
Hence, all values of x that satisfy 2x+2/x+7 >= 0 are represented as x >= -1
See attachment for the number line of x >= -1
