a ski club planned a trip to lake tahoe, and 40 of the members signed up to go. if this is 60% of the club, how many members does the ski club have in total? explain how you got the answer
a. 67
b. 240
c. 17
d. 73

Since the number of members attending is 40, you can eliminate 17 as a possible answer, as it is smaller than 40. You can also eliminate 240 because 40 members is 60%, so the answer must be less than 80. You are now left with 67 and 73. 

It is (a) because 40 divided by 67 = 0.597. 0.597 x 100 = 59.7% which is rounded to 60% of the club
