Yolanda's club requires that 60% of the members be present for any vote. If at least 40 members must be present to have a vote,
Dmitry [639]
Hi! So at least 60% of the members must be present, and that number is at least 40. To find the total amount of members, we can write and solve a proportion. Set it up like this:

40/x = 60/100

This is because we are looking for the total amount numbers and we already know the part. Cross multiply the values. 40 * 100 is 4,000. 60 * x is 60. You get 4,000 = 60x. Now, divide each side by 60 to isolate the x. 4,000/60 is 66.666667 or 67 when rounded to the nearest whole number. x ≈ 67. Yolanda's club currently has 67 members.
