Jane's and Mariah's savings in the long run Remains same

Step-by-step explanation:

x(years)                                     1           2         3

f(x) = 2x

Jane's savings in dollars          2         4          

g(x) = 2x

Mariah's savings in dollars       2          4            

f(x) = 2x

=> f(3) = 2 * 3 = 6

g(x) = 2x

=> g(3) =2 * 3 = 6

x(years)                                     1           2         3

f(x) = 2x

Jane's savings in dollars          2         4          6

g(x) = 2x

Mariah's savings in dollars       2          4          6  

Jane's and Mariah's savings in the long run Remains same

The savings will increase by the same factor for both

I hope this is what you wanted:

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
