The solution to the system of equations from the graph is x = 285.7 and y = 214.3
An equation is an expression that shows the relationship between two or more numbers and variables.
Let y represent the the volume of milk he uses and x the volume of whipping cream he uses. Hence:
x + y = 500 (1)
Also:
0.18x + 0.04y = 500(0.12) (2)
From the graph:
x = 285.7 and y = 214.3
The solution to the system of equations from the graph is x = 285.7 and y = 214.3
