Answer:
The number of nickels, x is 4
The number of dimes, y is 16.
Explanation:
Given that Melanie has $1.80 worth of nickels and dimes, and she has 12 more nickels than dime.
Let x represent the number of nickels and y represent the number of dimes.
Then we have:
0.05x + 0.1y = 1.80 ...................................................(1)
x + 12 = y.....................................................................(2)
Solving these equations using graph as follow:
Note that the solution are the points where the lines intersect.
Here, x = 4 and y = 16
