Victoria has some money from her birthday and the amount is modeled by the function h(x) = 200. she read about a bank that has savings accounts that accrue interest according to the function s(x) = (1.05)x − 1. victoria is thinking about putting her money into the savings account to gain interest. using complete sentences, explain to victoria how she can combine her functions to create a new function, and explain what this new function means.

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
