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.
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.
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).
