Eileen has a greenhouse and is growing orchids. the table shows the average number of orchids that bloomed over a period of four months: month 1 2 3 4 orchids 11 12.4 13.8 15.2 did the number of orchids increase linearly or exponentially?

9514 1404 393

  linearly

Step-by-step explanation:

The month-to-month difference in the numbers of orchids is 1.4, so the increase is linear.

If the numbers of orchids had a constant ratio, and/or if the differences had a constant ratio (not 1), then the relation would be exponential.

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
