Muhammad buys a toy for $18 plus a 9% tax. Alexander buys a hat for $15 plus a 9% tax. Enter the difference in the amount Muhammad and Alexander paid, including tax. Round your answer to the nearest cent.

$3.27

Step-by-step explanation:

109% of the cost is to be paid

109% = 1.09

Muhammad: 1.09(18) = 19.62

Alexander: 1.09(15) = 16.35

19.62 - 16.35 = 3.27

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
