Andrea writes a down a number , k. i write down a number that is 4 less than 5 times andrea's number. if the sum of our numbers is 14, find the two numbers.

Givens

Andrea: K

Me: 5k - 4

Sum

k + 5k - 4 = 14

Solve

6k - 4 = 14              Add 4 to both side.

6k - 4 + 4 = 14 + 4

6K = 18                  Divide by 6

k = 18/6

k = 3

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
