Answer:
112
Step-by-step explanation:
Honestly I read the question wrong, but yea listen to the person above. I just woke up lol
Increasing by 30% results in multiplication by 130/100, or 13/10. Setting the original amount of students to x, we write the equation:
13x/10=182
We multiply by 10 for a result of:
13x=1820
Dividing by 13, we have:
x=140
Thus, 140 students were in the club last year.
"Why?" in math has various meanings.
Let's solve
5x +1 > 4x + 1
That's easily solved,
5x - 4x > 1 - 1
x > 0
Since x>1 is included in x>0, it's in the solution set to the above inequality, so all such x make the inequality true.
