Question

Harrison has 12 coins in quarters and nickels. He determines that they have a total value of $2.00.
a) Write a system of equations that could be used to find the number of each coin he has.

Answer 1

Answer:

• See below

Step-by-step explanation:

Let the number of nickels is n, number of quarters is q.

We know that:

• Nickel = 5¢, quarter = 25¢, $2 = 200¢

As per given we can set the following system:

• n + q = 12
• 5n + 25q = 200

Solving this we get:

• n = 5, q = 7
