The expression shown can be used to calculate the amount of money in dollars a grocery store customer should receive in change when paying with $50. 50 - (14 + 12 + 2(5) + 2(2) + 3)

What amount of change in dollars should the customer receive?

7$

Step-by-step explanation:

Do the parenthesis work first (following PEMDAS). 14+12+10+4+3=43 50-43=7.

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
