Hiram takes an Uber from his house to the alrport. The Uber driver charges $3.50 initial fee plus $7.25 per mile. Write the equation that can be used to find y, the total cost of the trip, If x
represents the number of miles in the trip? (Do not include $ in your equation).

y = 7.25x + 3.50

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
