Question 1147867

Kylee has $0.80 in nickels and dimes. She has four more nickels than dimes. How many of each coin does she have? 

I just need help on getting the equations right. From there on, I can figure out whether to use substitution or elimination and do the work.
<pre>One of the other person's equations is WRONG! 
Correct equations: N = D + 4, or N - D = 4, or D = N - 4 ------ eq (i)
.05N + .1D = .8 ------ eq (ii)
Substitute N - 4 for D in eq (ii) to get value of N, or the number of nickels
Substitute the value of N into eq (i), which is the EASIER one, to get the value of D, or the number of dimes.
Last 2 lines could be omitted since you claim that you know how to solve the equations, and only need the setup.
