$1.8

Step-by-step explanation:

divide .45/2 and get .225

multiply this by 8 and get 1.8

it would cost 1.8n

$1.80

Step-by-step explanation:

45/2 = 22.5 cents per pencil

0.225 × 8 = $1.8

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
