Question 560197: An insecticide contains 80 centigrams of inert ingredient for every 1 centigram of active ingredient. If the quantity of the insecticide weighs 243 centigrams, how much of each type of ingredient does it contain?
Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! Let x = amount of active ingredient
80x = amount of inert ingredient
243 = total amount of insecticide
x+80x = 243
81x = 243
x= 3 centigrams of active ingredient
80x = 240 centigrams of inert ingredient

Near the top of my Homepage, look for the link called "Basic, Intermediate, and College Algebra: One Step at a Time." Choose the "Basic Algebra" link, and look in "Chapter 1" for "Sections 1.09 and 1.10" on Word Problems. You will really like the "MATH IN LIVING COLOR" sections that go with these sections, where many of the hardest problems are solved for you in COLOR.
I have explanations on most topics from algebra that might be easier for you to understand than your own textbook. The entire website is FREE!! If anyone needs help finding a page on my website, send me an Email at rapaljer@seminolestate.edu.
