At a local pizza shop, 2 small pizzas, a liter of Pepsi, and 3 salads cost $20.

4 small pizzas, 2 liters of Pepsi and 1 salad cost $25.

3 small pizzas, a liter of Pepsi and 4 salads cost $28.

What is the cost of each item separately?

• 2p + 2p + 2s = 20

  4p + 4p + 4s = 25

  3p + 3p + 3s= 28

• 2p + 1p + 3s = 20

  4p + 2p + 1s = 28

  3p + 1p + 4s= 25

• 1p + 1p + 1s = 20

  1p + 1p + 1s = 25

  1p + 1p + 1s= 28

• 2p + 1p + 3s = 20

  4p + 2p + 1s = 25

  3p + 1p + 4s= 28
