Question

Hunter has a total of $9.60 in dimes and nickels. Let d be the number of dimes and n be the number of nickels.

When the money values are in cents, the situation is modeled by the given equation.

How many dimes does Hunter have?

Hunter knows there are 12 more dimes than nickels. This fact is modeled by the given equation.

58

Answer 2

Solve the system of equations to find how many coins of each type Hunter has.

First, substitute the expression (n + 12) for d in the first equation to write a single equation that can be solved for n.

So, Hunter has 56 nickels.

Now, substitute 56 for n in the second given equation and solve for d.

So, Hunter has 68 dimes.
