select the system of equations that represents this situation use c to represent the cost of a cup of coffee and w to represent the cost of a bottle of water
7 cups of coffee and 2 bottles of water cost $16
8 cups of coffee and 3 bottles of water cost$19
a) c+w=20
7c+2w=16
b) 7c+8w=16
2c+3w=19
c) 7c+2w=16
8c+3w=19
d) 2+7w=16
3c+8w=19

The system of equations that represent this situation is 7c + 2w = 16 and 8x + 3y = 19

Let c represent the cost of a cup of coffee and w to represent the cost of a bottle of water

7 cups of coffee and 2 bottles of water cost $16, hence:

7c + 2w = 16   (1)

8 cups of coffee and 3 bottles of water cost $19, hence:

8x + 3y = 19      (2)

The system of equations that represent this situation is 7c + 2w = 16 and 8x + 3y = 19
