One day in january, the high temperature was −3.6∘ and the low temperature was −22.3∘ .

what was the difference between the high and low temperatures that day?

enter your answer, as a decimal,

18.7∘

Step-by-step explanation:

The difference between the high and low temperatures that day is the gap between the recorded figures on the number line.

The difference can be derived from;

Let the difference be d

d = −3.6∘ - −22.3∘

In algebra, - × -  = +

Therefore,

d = −3.6∘ - −22.3∘ = −3.6∘ + 22.3∘

d = 18.7∘

The difference between the high and low temperatures that day is 18.7∘.

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
