1. A box contains 5 times as many dimes as nickels. The total amount in the box is $2.20. How many coins of each type are in the box?
2. In Ken’s pocket there are 3 times as many quarters as dimes. In all he has $1.70 in coins. How many coins of each type does he have?
3. There are twice as many nickels as pennies and 5 times as many dimes as pennies in Joan’s drawer. In all she has $1.22. How many coins of each type does she have?
4. Monica has three times as many nickels as pennies and twice as many quarters as nickels. In all she has $3.32. How many coins of each type does she have?
Solve each system.
5. Mitch put $4.55 in dimes and quarters on his desk. He has 7 more quarters than dimes. Find the number he has of each coin.
6. If Sue has $1.45 in nickels and dimes, and the number of dimes exceeds the number of nickels by 4, how many nickels and how many dimes does she have?
7. Constance has $2.80 in quarters and dimes. The number of quarters exceeds three times the number of dimes by 1. Find the number she has of each kind.
8. Wanda gave $5.30 in nickels, quarters, and dimes to her little daughter. The number of dimes exceeded the number of nickels by 3, and the number of quarters was 20 less than the number of nickels. Find the number of each kind of coin she gave to her daughter.
