Question

monica was told her IQ was at least 78,but at most 115. Let q stand for Monica's IQ, and write an inequality for this situation?

Answer 1

this is an inequality where you have monica's iq as the variable, lets call it Q. She was told that her iq was at least 78. At least means greater than or equal to. so Q is greater than or equal to 78. She was also told that her iq was at most 115, meaning Q is less than or equal to 115. Expressing these as seperate equations gives this:
Q>=78 and Q<=115

we can combine these because Q must be between 78 and 115 (inclusive). so we can write this as 78<=Q<=115.
