HELP ME PLZ! :3 It cost $83 a day to rent a car plus a required fee for insurance. Suppose the total cost for renting a car for 7 day is $621.
Part A: Write an equation to model this situation.
(Write the equation in slope-intercept form)
Part B: How much does the insurance cost?

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
