Hello from MrBillDoesMath!
Answer:
z = 28 (y/x)
Discussion:
"
z varies inversely with x and directly with y" translates into
z = k * (y/x) (*)
Substituting x = 2, y = 3, z = 42 in (*) gives
42 = k (3/2) => multiply both sides by 2/3
42 (2/3) = k (3/2)(2/3) => 42(2/3) = 28; (3/2)(2/3) = 1
28 = k
Conclusion:
z = 28 (y/x)
Thank you,
MrB
To find a % you want to divide the # of new members, by the total # of members.
14/34 =0.41
Since this gave you a decimal, multiplying by 100 will give you a %!
0.41 x 100 = 41%
This means that 41% of the club is new members!
