20 ! the first five terms in a pattern are shown below. -0.5, -0.25, 0, 0.25, 0.5, . . if the pattern continues, which expression can be used to find the nth term? a) 0.75n - 1.25 b) -0.25n - 0.25 c) 0.25n - 0.75 d) -0.5n + 0.25

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
