For a trapezoid, the following formula relates the area a, the two bases a and b, and the height h. a=1/2h(a b) solve for b.
A)
1/2 hA - B
B)
1/2 hB - A
C)
2A - B/h
D)
2A/h - B

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

a. is correct

its adding 5.5 each time
