Karen owns a seafood restaurant. She orders trout from an online retailer. Each pound of trout costs $32, and the company charges a $4 fee for

shipping the order. However, if Karen orders 10 or more pounds, the trout

costs only $25 per pound, but the shipping fee is $9.

Which piecewise function models the cost of x pounds of trout?

F (x) = {32x+4, 0 < x < 10

25x + 9, x _> 10

Step-by-step explanation:

sorry if I’m wrong!

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

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
