Ishi bought a canvas and 6 tubes of paint for $24.45. If the canvas cost $6.45, how much did each tube cost?

it is 3

Step-by-step explanation:

you take the cost of the canvas( 6.45) away from the total amount(24.45).

the answer is 18( the total of the 6 tubes)

now to find the cost of one tube you divide the total cost of the tubes(18) by the amount of tubes(6)

you wpuld get 3 the cost of one tube of paint              

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
