Christy has a coin collection consisting of nickels and dimes. She has 28 coins worth $2.25. How many of each coin does Christy have?

• N + D = 225

  5N + 10D = 28

• N + D = 28

  N + D = 225

• 5N + 10D = 28

  5N + 10D = 225

• N + D = 28

  5N + 10D = 225

Tania had 35 coins in pennies and nickels. She had $1.03. Which system of equations could be used to determine the number of coins she has?

• .01p + .05n = 35

  p + n = 103

• 1p + 5n = 1.03

  p + n = 35

• .01p + .05n = 1.03

  p + n = 35

• .05p + .01n = 1.03

  p + n = 35

I have a total of $2.25 in dimes and nickels. I have twice as many dimes as nickels.

Which system of equations could be used to determine how many of each kind of coin I have?

Let d = number of dimes I have and

n = number of nickels I have.

• 0.10d + 0.05n = 2.25

  d = 2n

• 0.05d + 0.10n = 2.25

  d = 2n

• 0.10d + 0.05n = 2.25

  n = 2d

• 0.05d + 0.10n = 2.25

  n = 2d

Dennis mowed his next door neighbor’s lawn for a handful of dimes and nickels, 80 coins in all. Upon completing the job he counted out the coins and it came to $6.60. Write a system of equations could be used to find d, the number of dimes, and n, the number of nickels.

• d + n = 6.60

  .10d + .05n = 80

• d + n = 80

  d + n = 6.60

• d + n = 80

  .10d + .05n = 6.60

• d + n = 80

  .05d + .10n = 6.60

Lizzy has 30 coins that total $4.80. All of her coins are dimes, D, and quarters, Q. Which system of equations models this situation?

• D + Q = 4.80

  0.10D + 0.25Q = 30

• D + Q = 30

  0.10D + 0.25Q = 4.80

• D + Q = 30

  0.25D + 0.10Q = 4.80

• D + Q = 4.80

  0.25D + 0.10Q = 30
