B) Work out 4 1/2 + 1 1/2
Give your answer as a mixed number in its simplest form.

10

Step-by-step explanation:

4 1/2 + 11/2

= 9/2 + 11/2

= 20/2

= 10

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
