Question 954070: I've tried to answer this question, but i get one positive solution for apples, and negative solutions for orange & pears, which given the context of the problem, doesn't make sense (for question #1) ). #2 once again doesnt make sense.
> Apple is made up of 20mg zinc, 30mg potassium & 15mg Radium
> Orange is made up of 20mg zinc, 50mg potassium & 10mg radium
> Pear is made up of 20mg zinc, 10mg potassium, & 10mg radium
question #1: you need 115mg zinc, 120mg potassium, 110mg of radium everyday, so how many of each fruit should you eat?
question #2: How many of each fruit do you eat if the mg of zinc in each fruit is cut by 1/2 ?
For #1, I set it up as follows:
FRUIT Apple Orange Pear Total
Zinc 20 20 20 115
Potassium 30 50 10 120
Radium 15 10 10 110

You can put this solution on YOUR website! I think you had this problem up here previously, and I checked the matrix that you had on my calc, and I did indeed obtain negative values:
Apples; 10.5
Oranges: -3.68-
Pears: -1.06---
:
Decided it was just a screwed up problem. Don't waste your time on it.
