A survey on healthy choices was given to gym members at Work It Out. The results showed that 90% of its members drank protein shakes. Of the members who drank protein shakes, 30% took weight-loss medication whereas only 10% of members who did not drink protein shakes took weight-loss medication.

Answer:

63%

Step-by-step explanation:

First, create an easy number to start being able to grasp the concept.

Let us start with 100 members of "Work it Out"

90% drank protein shakes, which translates to 90 people.

30% of 90 people took weight loss medication, this is equal to 27 people. The 10% of the members that didn't take protein shakes (10) took weight loss medication. Add 10 to 27, then subtract from 100 to get the people that don't use weight loss medication. This gets us 63, then put over the total number of members to get 63%.

Hope this helps, and please mark me brainliest! :)
