Add 6 to both sides: 7x>28
Divide both side by 7: x>4
x>4 means that all x-values that are greater than 4 will work. Therefore you would write an open dot at x=4 on the number line to show that 4 isn't included, and draw an arrow going right to show all possible solutions greater than 4.
Start by finding 7% of the $23.20:

Now add this to $23.20:

Now, let's find 18% of this new total with tax to find the tip amount:

This is the tip amount. And finally, let's add this to the 24.824:

Not sure if you were given any instructions about rounding, but Ana's cost will be around $29.29.
