the correct answer would be t ≤ 14 becasue it says she will run less than 36 miles, she wont run more or greater miles this week meaning greater to or equal is incorrect.
I hope this helped :)
The question says they will run less than 36 miles, so this means they will run up to 35 miles.
They have run 22 so far, so t will be less than or equal to 35 - 22
T is less than or equal to 13.
