Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
Point (7, 0)
Equation y = x - 7
<u>Step 2: Find</u>

- Subtract: 0 = 0
Since 0 = 0 is true, then it would be a solution to the equation.
If what you mean by the "percent of people 50 years old belong to group A" is the percentage of 50-year old people with respect to the total number of people belonging to group A, then the answer is
32/(19+32) * 100 = 63%
But, if what you mean is the percentage of 50-year old people in group A with respect to the total number of 50-year old people, then the answer will be
32/(32+24) * 100 = 57%
