n ---> number of nickels
d ----> number of dimes
0.05n + 0.1d = 3.50
n + d = 50
This needs to be solved and put in equation form. Seems simple but not sure if I am figuring it right.
Jill has $3.50 in nickels and dimes. If she has 50 coins, how many of each type of coin does she have?
use the equations and solve
n ---> number of nickels
d ----> number of dimes
0.05n + 0.1d = 3.50
n + d = 50
