I need to use inequality symbols to solve this statement: The number of children (variable N) is between 30 and 50 inclusively

OpenStudy (campbell_st):

N is between... so the inequalities go in the same direction.... and must include 30 and 50.. but not greater than or less than so its \[30 \le N \le 50\]
