Madison spent 5/8 of her savings on microwave oven and refrigerator. she used for sevens of the amount she spent to buy refrigerator. the refrigerator cost within $280 worth in the microwave oven. how much savings did madison start with?

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

answer: y = -2.5x - 15

              (-6,0)
