Question

Spleen contains 54% lead and dandelion contains 12% lead. If spleen is combined with extracts of dandelion, the result is an antidote called Nux Mys. How many ounces of dandelion root extract must be mixed with 30 ounces of spleen to make 30% lead-nux mys?

Answer 1

Hi Gabby,

 

Let x = number of oz of dandelion root needed.

 

ING   # oz •  conc  =  

 

DR       x    •   .12  =   .12x

S        30   •   .54  =   16.2

 

N-M (x + 30) •  .30 = .30(x + 30)

 

.12x +(.54 x 30) = .30(x + 30)

 

x = 40 oz
