A population of 40 foxes in a wildlife preserve quadruples in size every 13 years. The function y=40•4x​, where x is the number of 13​-year ​periods, models the population growth. How many foxes will there be after 26 ​years?

640

Step-by-step explanation:

y = 40(4)^x

x = 26/13 = 2

y = 40(4)^2

y = 40 (16)

y = 640

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
