Question

In 2010, there were about 246 million vehicles (cars and trucks) and about 308.7 million people in the United States.1 The number of vehicles grew 15.5⁢ % over the previous decade, while the population has been growing at 9.7⁢ % per decade. If the growth rates remain constant, when will there be, on average, one vehicle per person?

Answer 1

Answer:

2054

Step-by-step explanation:

The equation for the growth of people = 308.7(1097)^x

The equation for the growth of vehicles = 246(1155)^x

If the number of both are equal tham

308.7(1097)^x=246(1155)^x

Dividing both sides by 246

1.254878(1097)^x=(1155)^x

Dividing both sides by (1097)^x

1.254878=(1155÷1097)^x

X=4.406 decades

X=44 years
