Answer: She has 40 nickels and 40 quarters .

Step-by-step explanation:

Let be "n" the number of nickels Theresa has and "q" the number of quarters Theresa has.

You know that she has a total of $12 in nickels and quarters. In cents, this is:

\$12*100=1,200\ cents

Then, based on this you can write the following expression:

5n+25q=1,200

Since n=q, you can rewrite it as:

5n+25n=1,200

Solving for "n", you get:

30n=1,200\\\\n=\frac{1,200}{30}\\\\n=40

Therefore she has 40 nickels and 40 quarters .
