Question

In 2010, the estimated population of Los Angeles was 3.79 × 106 people. The population of California that same year was about 9.84 times this number. Which expression shows the approximate population of the state of California in 2010?

Answer 1

The approximate population of the state of California in 2010 was
`37,293,600\ people`

Explanation:

Let

x----->the estimated population of Los Angeles in 2010

y----->the estimated population of the state of California in 2010

we know that

`y=9.84x` ------> equation A

we have

`x=3.79*10^(6)\ people`

Substitute the value of x in the equation A and solve for y

`y=9.84(3.79*10^(6))=37.2936*10^(6)\ people`

`37.2936*10^(6)=37,293,600\ people`

Answer 2

3.73 × 10^7 people

Explanation:

The original equation 3.79 × 10^6 = 3790000. 3790000× 9.84=37293600. 37293600 estimated is about 37300000. That would make 3.73 × 10^7 the expression that represents the amount of people in California.
