For this case we must solve the following inequality, finding the values for the variable "t":
[tex]t + 18 <43[/tex]
We subtract 18 from both sides of the inequality:
[tex]t + 18-18 <43-18\\t <25[/tex]
Thus, the variable "t" is defined for all strict lower values than 25.
Answer:
[tex]t <25[/tex]
Option A
