june has been saving nickels and dimes for three weeks in a jar.  She looked into the jar and found that it contained 29 coins worth $2.05. how many nickels and dimes were in the jar?

anonymous · Answer

You can set up a system of equations:
.1d + .05n= 2.05
d+n = 29

where d is the number of dimes and n is the number of nickels

anonymous · Answer

but yes how do u solve for d and n???

anonymous · Answer

Well, you can take the easier one and solve for one variable and plug it into the other

anonymous · Answer

so d=29-n

anonymous · Answer

Then you plug in that d into the other equation so that you have only one variable to get the number of nickels
