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.
5 cups of coffee and 2 bottles of water cost $12.
4 cups of coffee and 7 bottles of water cost $15.
OA. c + w = 18
5c+7w = 12
о B. 5c+ 2w = 12
4c+ 7w = 15
OC. 2c+5w = 12
7c+ 4w=15
о D. 5c+ 4w = 12
2c + 7w = 15

The answer is C.
5c+2w= 12
(5 x 2 )+(2 x1)=12
10 + 2 = 12

7c + 4w=15
(7x1) + ( 4x2) = 15
7 + 8 = 15

Hope this helps. :)
