If the folder cost $2 and the notebook cost 4 times that then the notebook cost $8

If the notebook cost 2 times the cost of a set of pencils and a notebook cost $8 then a set of pencils cost $4 (half the cost of the notebook)

We already know the cost of the folder is $2 and we need one of each idem: Folder=$2  Notebook=$8  Pencils=$4 

2+8+4
10+4
14

The total is $14

What two numbers add to 10 and multiply to -192? How do you find it?
Levart [38]
There is a way to do this algebraically using equations, but it is really messy so I am going to go over the way to do it. The way you do this is by finding whole numbers that multiply to make -192. Start with 1 and 192, 2 and 96, 3 and 64, etc and make the smaller number negative. 
The reason why you make the smaller number negative is because we are looking for what numbers add together to make a positive number (10). If the bigger number was negative, then we would get a negative sum. 
From what i could find, there aren't any whole numbers that satisfy this, and i doubt that the question would want you to find decimals for this. 

The way to find this with equations (in short) is to have to variables, x and y, and make two equations. in this case x+y=10 and xy=-192. Solve one equation for a variable and then use substitution to plug that variable into the other equation. if you do this you get really long decimals.
