Question

in 2020 there were about 282 million gas powered cars on the road this number is expected to decrease at a rate of 3.1% per year if this is correct estimate how many people will be driving gas in 5 years

Answer 1

≈ 240,000,000 people

Explanation:

`3.1 \cdot 5 = 15.5`

`15.5` ≈
`16`

`Y = X(1 - P\%)\\Y = 282,000,000(1 - 16\%)`

`p = 16\%/100 = 0.16\\Y = 282,000,000(1 - 0.16)\\Y = 282,000,000(0.84)\\Y = 236,880,000\\`

`236,880,000` ≈
`240,000,000`
