Given:

Total members = 400

Percentage of members 17 and younger = 8%

Percentage of members aged 18 - 34 = 31%

Percentage of members aged 35 - 54 = 35%

Percentage of members aged 55 plus = 26%

To find the number of members between the ages of 18 and 34, use the formula below:


\text{Number of members aged 18 and 34 = percentage aged 18 and 34 }\ast\text{ Total members}

Thus, we have:


\text{Number ages 18 and 34 = }(31)/(100)\ast400=0.31\ast400=124

Therefore, the number of health club members at this health club between the ages of 18 and 34 is 124
