assume that last year the consumer price index indicates that inflation was 3%. If new cars increase in price by the rate of inflation, how much will a $30,000 car increase in price?

900 dollars

Step-by-step explanation:

30,000 is the amount that it was, so we are looking for the amount that it will increase. 3 percent can be written as 0.03 times 30,000 gives you 900

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

$12. that is my answer.
