Answer: A: sorry if I'm wrong but that's what I was told
Step-by-step explanation:
Given that 27 12th grade students have 2 colleges in mind and 23 12th grade students are considering 3 colleges or more. If there are 170 students in 12th grade, the percentage of the twelfth grade students that have more than one college in mind is given by:
2 less than a number n is (n - 2 ) and 3 times this is 3(n - 2 ), thus
3(n - 2) ≥ 5n ( greater than or equal to 5 times n )
3n - 6 ≤ 5n ( subtract 3n from both sides )
- 6 ≥ 2n ( divide both sides by 2 )
- 3 ≥ n or n ≤ - 3
Since n is less than or equal to - 3 use bracket ]
n ∈ ( - ∞, - 3 ] ← solution set
