3(t-y)
The expression that represents "three times the difference between t and y" is
"It is a mathematical statement which consists of numbers, variables and some mathematical operations."
For given question,
We need to write an expression for the statement "three times the difference between t and y"
The statement "the difference between t and y" in mathematical expression form would be t - y
Now, we write "three times the difference between t and y" in expression form as,
Therefore, the expression that represents "three times the difference between t and y" is

b) f(x)= 150+50x over 2+x
c) f(x)= 300+50x over 1+x
d) f(x)= 300+50x over 2+x
Answer: d) f(x)= 300+50x over 2+x
Step-by-step explanation:
Since, the money earned by a teacher in selling a book = $ 150
⇒ The money earned by 2 teacher = $ 300
Now, the money earned by a student in selling the book = $ 50
⇒ The money earned by x students = 50x
Thus, the total collection by 2 teacher and x students = 300 + 50x
And, the total persons = 2 teachers + x students = 2 + x
⇒ Option d) is correct.
