Skill: Count collections of coins

Each kind of coin has a fixed value:

• Penny: $1$ cent
• Nickel: $5$ cents
• Dime: $10$ cents
• Quarter: $25$ cents

To find the total value, multiply the number of each coin by its value, then add.

Example: Find the value of $3$ pennies, $2$ nickels, $1$ dime, and $2$ quarters.

1. Find the value of each group:

   • $3$ pennies: $3 \times 1 = 3$ cents
   • $2$ nickels: $2 \times 5 = 10$ cents
   • $1$ dime: $1 \times 10 = 10$ cents
   • $2$ quarters: $2 \times 25 = 50$ cents

2. Add the group values:

$$3 + 10 + 10 + 50 = 73\text{ cents}$$

3. Write the total as dollars and cents. Since $100$ cents equals $1$ dollar, $73$ cents is:

$$\$0.73$$

So, the collection is worth $73$ cents, or 0.73$.
