Evaluate the limit using techniques from Chapters 1 and 3 and using L'Hôpital's Rule. lim x→8 x + 41 − 7 x − 8 Exercise (a) (a) Using techniques from Chapters 1 and 3 Step 1 The limit to be evaluated is lim x→8 x + 41 − 7 x − 8 . By directly substituting we have the following. lim x→8 x + 41 − 7 x − 8 = 0 Thus, the direct substitution results in ---Select--- form.

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
