Devon found that for every 4 miles he walks, he needs one bottle of water. He plotted his water usage on a graph but left out some possible points. On a coordinate plane, the points (4, 1) and (12, 3) are plotted.

(8, 2)

Step-by-step explanation:

(4, 1)+(4, 1)+(4, 1)=(12, 3)

(4, 1)+(4, 1)=(8, 2)

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

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
