Hi Vicky, When I looked at this I got a pencil and wrote what is given using symbols to shorten what I had to write. I let T for the number of ten dollar bills Chris had, D for the number of dimes, P for the number of pennies and L for the number of one dollar bills. (I had already used D for dimes and I am in Canada where we have a one dollar coin we call a loonie, hence the L.). The three statements you have are
From this you can see that if you know T you can find D and from D you can find P and then L. You didn't give any other restriction so it looks like I can choose T to be anything I want. For example it T = 1 then D = 2, P = 4 and L = 8. Similarly if T = 5 then D = 10, P = 20 and L = 40. In fact you might have T = 0 and then D = P = L = 0 and poor Chris is broke. Do you have any other information? | ||||||||||||
