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

Answer:

The number of members the ski club have in total are:

                    Option: a  

                      a.  67

Step-by-step explanation:

A ski club planned a trip to Lake Tahoe, and 40 of the members signed up to go.

Now these 40 members constitute to the 60% population of the club.

Let x be the total number of members in the ski club.

This means that:

[tex]60\%\ of\ x=40\\\\i.e.\\\\\dfrac{60}{100}\times x=40\\\\i.e.\\\\x=\dfrac{100\times 40}{60}\\\\i.e.\\\\x=66.67[/tex]

as number of members of the club can't be in decimals.

Hence, it is approximately equal to 67.

Hence, the number of members are: 67
