Good morning!
So obviously, since the minute hand is on the number 12 (using a traditional clock), we know that Tyrone eats at the beginning of a new hour (06:00, 15:00). Using the word "dinner" as a clue, we can assume he is eating during the later hours of the day, meaning he could be eating anywhere towards the evening. In this case, using all the information, we can assume Tyrone is eating at either 17:00, 18:00, 19:00 ... 21:00, since those are the most "common" times for eating dinner.
(Common core is weird, man...)
Hope this helps,

Answer:
Percent markdown = 14%
Step-by-step explanation:
Given:
Original price of DVD player = $175.90
Markdown price of DVD player =$153.77
To find percent markdown.
Amount of mark down 
Percent markdown 
Let's say a = number of ordered soups, b = number of ordered sandwiches.
Then 4.5a + 7.75b = 113.50, and a and b are integers between 0 and 18 inclusive.
How do we tackle this? If all ordered soup, the cost would be $81, so we'll have at least 4 sandwiches. If all ordered sandwich, the cost would be $139.5, so at most 15 sandwiches were ordered. You also know an even number of sandwiches was ordered, to let the price end at 50 cent.
If you brute-force from 4,6,8,10,12 to 14 sandwiches, you find the answer at 10 sandwiches and 8 soups.
10*7.75 + 8*4.50 = 113.50
