You spend $40 on 5 pounds of concrete. What is the unit rate in dollars per pound?

6 dollars per pound

Step-by-step explanation: since you have 5 pounds of concrete you just divide 40 by 5 and then you get 6.

8$/lb

Step-by-step explanation:

because 8x5 is 40 there for each pound would be 8$ if there are 5 pounds

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
