The value of 10 coins is $1.10. If the coins are made up of quarters, q, and dimes, d, which of the following systems could be used to determine how many quarters there are?

• d + q = 1.10

  0.10d + 0.25q = 10

• d + q = 10

  0.10d + 0.25q = 1.10

• d + q = 10

  0.25d + 0.10q = 1.10

• d + q = 1.10

  0.25d + 0.10q = 10

Which of the following systems will represent the following: Amber is having a cookout. She needs to feed 10 people hotdogs, x, and hamburgers, y. She only has $24. Hotdogs cost $2 each and hamburgers cost $3. How many of each can she buy?

• x + y = 24

  3x + 2y = 10

• x + y = 10

  3x + 2y = 24

• x + y = 24

  2x + 3y = 10

• x + y = 10

  2x + 3y = 24
