Question

In the state of Indiana, 302500 people don't drive. If this is 5% of the population of Indiana residents aged 5 years and older, estimate the population of Indiana residents aged 5 years and older. Express your answer rounded to the nearest hundredth of a million.

Answer 1

Answer: 6,050,000

Explanation:

5%=0.05

302500/0.05=6,050,000

Answer 2

x = 6050000

Explanation:

Set up a proportion

5% = 302500 people

100% = x

5/100 = 302500

100/100 = x Cross multiply

5x / 100 = 302500 * 100/100 Multiply both sides by 100

5x / 100 * 100 = 302500 * 100 / 100 *100 Do the multiplication

5x = 302500 * 100 Combine the right.

5x = 30250000 Divide by 5

5x/5 = 30250000/5

x = 6050000

1/100 of a million is the 5. It is already rounded to what it should be. So the answer is what we have.
