Eat-in Restaurant Total Cost

You have to pay at least $55.00, but you can also tip your waiter, so the total cost could be more. I closed my dot because you don't have to tip your waiter, and you can just pay 55$, or you can tip the waiter any amount, and then you would add that amount to 55$ bill to get your total cost. (Which would have to be greater than fifty five dollars, because you can't tip the waiter a negative amount.

R-rated Movie

You have to be 18 years old or older to watch an R rated movie. You have to be at least 18 to watch this movie, and you could also be over 18. My dot is closed because you can be 18 to watch this movie, and the line is pointing right because you can be older than 18.

Business Hours

The business is open from 1 pm to 6 pm on weekends. This means it's open at and after 1 pm, but before and at 6 pm. I closed both of my first dot only because the business is open at 1 pm, but it closes right at 6 o'clock. So t has to be greater than 1, but less than 6.

Driver's License

You must be 16 years old or older to have a driver's license. This means that your age has to be greater or equal to 16 to have a driver's license. I drew a closed dot because you could be equal to 16 years old, and I made the ray point to the right because you can also be greater than 16.

Speed Limit

You have to go at a speed less than or equal to 45 miles per hour. I closed my dot because your speed could be at 45 miles per hour (legally), and I have my ray pointed to the left because it could be at any speed below 45 miles per hour (unless there is a minimal speed, which I did not create in my example).
