Answer:
[tex]|T - B| \leq 2[/tex]
Step-by-step explanation:
Represent Tyler with T and Benjamin with B
Solving (a):
Since T is within 2 of B, then
[tex]T - B \leq 2[/tex] or [tex]B - T \leq 2[/tex]
These two inequalities can be merged to form:
[tex]|T - B| \leq 2[/tex]
There's no enough information to answer the B part
