Asingle person pays $6,600 in income taxes on a gross income of $33,000. how much would a single person be expected to pay if his gross income is $36,000?

Write and solve an equation of ratios:

$33,000 $6,600

=

$36,000 x

Then 33000x = 237600000, resulting in x = $7,200 (answer)

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
