There are two tanks at the aquarium. tank a and tank b. each has two sections. the volume of one section of tank a is 24 cubic feet. the volume of the other section of tank a is 96 cubic feet. what is the total volume, in cubic feet, of tank a? tank b has the same volumes as tank a. the volume of one section of tank b is 45 cubic feet. what is the volume, in cubic feet, of the other section of tank 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

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
