stephanie uses 4 meters of red yarn and 9 meters of purple yarn for a project. the red yarn costs $5 more per meter than the purple yarn. She pays a total of $72. What would be the combined cost of 1 meter of red yarn and 1 meter of purple yarn?

$13 for 1 meter of each color

1 meter of red yarn costs $9

1 meter of purple yarn is $4

sorry for the wait

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
