Lily adams purchased a $1,000 bond at 70. the bond pays 4%.
what was the cost of the bond?
what was the annual interest?
what is the yield (to the nearest tenth of a percent)?

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
