Answer:
Jack can take only 1 horse on his trailer to be towed by the truck without going over the maximum weight the truck.
Step-by-step explanation:
Given:
Weight of 1 horse = 1,200 lb
Weight of trailer = 2,700 lb
Jacks'truck can tow a maximum of 5000 pounds.
To find the maximum number of horses Jack can take in his trailer without going over the maximum weight his truck can tow.
Solution:
Let the maximum number of horses that Jack can take be = 
Using unitary method to find weight of
horses.
If 1 horse weights = 1,200 lb
Then
horses will weight in lbs = 
Total weight of horses and trailer in lbs = 
Since the maximum weight the truck can tow = 5,000 lb, so the inequality can be given as:

Subtracting both sides by 2700.


Dividing both sides by 1200.


From the inequality solution for
, we can conclude that Jack can take only 1 horse on his trailer to be towed by the truck without going over the maximum weight the truck.
