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.
f(x) = 20x² - 18x - 25
f(-1) = 20(-1)² - 18(-1) - 25
= 20 + 18 - 25
= 13
