We are given the following data:
Large boxes weigh 50 pounds each
Small boxes weigh 35 pounds each
There are 110 boxes
The truck is carrying a total of 4600 pounds
Solution
Let the number of large boxes be x, and the number of small boxes be y.
There are 110 boxes means:
The truck is carrying a total of 4600 pounds means:
We can solve the equations simultaneously to find x and y.
Solving simultaneously by graphical method, we have:
The graph shown above shows the point of intersection to be (50, 60)
Hence,
the number of large boxes is 50
the number of small boxes is 60
