An article estimates the average yearly cost of owning and operating a vehicle is $8,500. The article also stated, with 95% confidence, the margin of error for this estimate is $100. Determine the resulting 95% confidence interval for the average yearly cost of owning and operating a vehicle.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
