Jeff bought 7 pounds of chocolate
and spent $8.89. How much is one
pound of chocolate?​

1.27

Step-by-step explanation:

$1.27

Step-by-step explanation:

Divide the total cost by the number of things you have to get the unit cost. Unit cost is the amount per item

$8.89/7 items = $1.27 per 1 pound of chocolate  

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
