Question 877489: I need to put fungicide on my blueberries. The expensive stuff has active ingredient of 40%. What I have the same active ingredient is 2%. How much of the 2% do I need to use to equal the 40%?
y(2) = x(40)
2/40 = 20
multiply 2% x 20 to equal the 40%
so, 2 tsp x 20 = 40 tsp ??

20 times as much.

Does the expensive stuff cost 20x as much as the 2% ?
