Answer:
No, because James has confused the hours of watching tv with the hours of reading.
Step-by-step explanation:
This is incorrect. According to the graph, what we have is a point on the line at (6, 10), which implies that a student who reads for 6 hours will watch tv for 10 hours.
It is very likely that James is confusing the hours of watching tv with the hours of reading.
The first thing we must do for this case is to define variables:
w: pounds of meat
x: carton of milk
y: loaf of bread
z: cereal breakfast box
We write the system of equations:
0.70x + 0.60y + 0.50z + 1.50w = 10
x = 2y
z = y + 1
w = z
Solving the system we have:
w = 3
x = 4
y = 2
z = 3
Answer:
3 pounds of meat
4 cartons of milk
