enrollment in the ski/snowboard club increased by 30% this year. there are now 182 students in the club. how many students were
there last year?
1 answer:
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.
