Answer 1

Answer:

The answer to your question is letter C

Step-by-step explanation:

Data

hamburgers = h

fries = f

soda = s

Student 1         4h + 4f + 1s = 21

Student 2         1h + 1f + 1s = 5

Student 3         1h + 1f        = 5

From the data of students 2 and 3 we can conclude that the system will not have a solution because is not possible that one student has charged 3 items for the same cost of student 3 that bought only 2 items.

Answer 2

As per the text, 3 students buy the lunch n cafeteria and 1 student buys 4 hamburgers, 4 tries, and one soda, for 21$. Another student buys one hamburger, 1 tries, 1 soda for 5 dollars. The third one buys in the burger and $5 of fries.

• As per Student 1 equals to   4h + 4f + 1s = 21
• As per Student 2  equals to  1h + 1f + 1s = 5
• As per Student 3  equals to  1h + 1f        = 5

Hence the correct option is C.
