Susan put all her crayons in a container. of the 160 crayons in the container, 25% of them are red, 45% are blue, 10% are yellow, and 20% are orange which proportion can be use to find the total number of blue (b) crayons?

72

Step-by-step explanation:

cause you times 160x.45 you get 72

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
