What is the interval notation for the compound inequality? x≤3 or x>7
(−∞, 3) or [7, ∞)
[3,7)
(−∞, 3] or (7, ∞)
(3,7]

(-♾,3] or (7,♾)

i took the test

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
