Daniela rented a car. she paid a flat rate for the day, plus a cost per mile charge. the expression 0.15x+220.15x+22 represents the amount daniela paid. what do the different parts of the expression model? drag the parts of the expression into the boxes to match each description. daily flat rate cost per mile number of miles driven 22 0.15 x 0.15x

Let

x--------> the number of miles driven

y--------> the amount in dollars that Daniela paid

we know that

where

-------> represent the daily flat rate (the y-coordinate of the y-intercept of the linear equation)

-------> represent the cost per mile (the slope of the linear equation)  

---------> number of miles driven

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
