Using the proportion rule to solve this problem-is this correct?
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?
182x100=18200/30=607
607-182=425
answer 425

After you arrive at an answer, you need to do a sanity check. Your answer makes no sense. The problem says that the membership <u>rose</u> by 30% to 182. So how can you possibly accept the answer that last year it was <b>425</b>?
a proportion needs two ratios or fractions:
182/x = 1.30/1.00
