If 5 dozen roses can be purchased for $62.50, how much will 8 dozen cost?

Source: Net

Let x represent the cost of a dozen roses. 5 dozen roses can be purchased for $62.50 . Consider the following equation. 5x = $62.50. Here the product and factor are known, thus divide by the factor on both sides of the equation.

5x   $62.50

--  =     --

5     $12.50

Now to find out the cost of 8 dozens multiply the value of x by 8.

8x=8 ($12.50) = $100

Answer would be $100.

5x=62.50  Divide both side by 5  X=62.50/5  X=12.50   Now multiply the value  8x=8(12.50)  X=100  For 8 dozen roses it's $100  

only 10/60 isn't equivalent

hope this : )

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
