Acompany has determined that its weekly profit is a function of the number of items that it sells. which equation could represent the weekly profit in thousands of dollars, y, when the company sells x items? a. y^2=4x^2-100 b. y= -x^2+50x-300 c. x= -y^2+60y-400 d. x^2=-6y^2+200 hello! im curious about the process to answer this question, if you could include the process that would be great! ty

Eliminate answer choices C and D immediately, since we are not looking to solve for either x or x^2; rather, we want the weekly profit (y) when the company sells x items. Eliminate choice A, because we are not looking to calculate the profit squared. This process of elimination of unsuitable answers leaves us with answer choice B, in which y is the the weekly profit in thousands of dollars, y, when the company sells x items.

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
