Use the inequality symbols.

Basically, since t is at least 10,

t #>=# 10.

And since it is at most 22,

t #<=# 22.

So the final answer is: 10 #<=# t #<=# 22

Hope this helps you.

#10 <= t <=22#

'At least #10#', means that #t# can be equal to #10# or is more than #10#.

'At most #22#' means that #t# can be equal to #22#, but can also be less than #22#.

This gives the lower limit and the upper limit to the interval.

#10 <= t <=22#

#t =[10,22]#

We are told that #t# is at least 10 and at most 22.

Hence, #t>=10 and t<=22 -> 10<= t <=22#

This can be written in interval notation as:

#t =[10,22]#
