Suppose that y varies inversely with x. use the information to find k, and then choose the equation of variation. x = 13 when y = 100.

To solve this problem you must apply the proccedure shown below:

1. You have that varies inversely with and when the value of is .

2. Therefore, you can write the following expression, where is the constant of proportionality:

3. Solve for the constant of proportionality and substitute the values to calculate it:

4. The equation is:

The answer is:

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
