How would u find 20% of the regular price? what would you do with this amount to find the sale price

you would multiply the price by .20

Step-by-step explanation:

example:

20% of $160

sale, 20% off

160 x .20 = 32

$32 is 20% of $160, $128 is the sale price

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
