Question 384208: Translate to an equation:
h $100 bills and t $20 bills total $400
Graph the equation and use the graph to determine three different combinations of $100 bills and $20 bills that total $400.
(I have no idea how to do this please help me)
Answer by texttutoring(324)   (Show Source):
You can put this solution on YOUR website! Let h = number of hundred dollar bills
Let t = number of twenty dollar bills
the equation is:
100h + 20t = 400
Image that h is like the y-variable, and t is like the x-variable.
The graph would look like this: http://www.wolframalpha.com/input/?i=100y+%2B+20x+%3D+400

Try plotting this graph yourself on graph paper, and you should see a variety of combinations that are possible. Anything that falls on the line is possible.
For instance, if h=3, then t=5.
This makes sense because 100(3) + 20(5) = 400
Another possibility is if h=2, then t=10.
100(2) + 20(10) = 400
I will leave it up to you to find the last combination. Hint... keep going down the line as I've done.
