The graph shows the temperature of ice cream in an ice chest during an overnight trip. what is the domain of this function?

the domain is negative 10 through 30.

the domain is all integers from negative 10 through 30.

the domain is all real numbers 0 through 30.

the domain is all integers from 0 through 30.

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
