A solid dot on the graph of an inequality indicates that the number is contained within the inequality, so yo should use

or

to represent that situation, whereas a white dot indicates that the number is not contained within the inequality.
Our graph is telling us that

is greater or equal than -1, and also

is less than 3. So our inequality will be:
The waitress gets 45/75 = 3/5 of the tips
so waitress gets 3/5 * 350 = $210
To compare these two values, we need them to be in the same form.
To convert 20% into a decimal, we divide 20/100, or 0.20.
When comparing decimals, we know that 0.2 > 0.02.
Therefore, 20% > 0.02. (20% is greater than 0.02)
