Answer:
one cup of coffee costs $2, while one bottle of water costs $1
Explanation:
We can represent this using two equations:
- Variable x represents cups of coffee, and variable y represents bottles of water.
5x + 2y = 12
4x + 7y = 15
Your answer for the value of x and y should be
x = 2
y = 1
Therefore, one cup of coffee costs $2, while one bottle of water costs $1.
