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 = [tex]x[/tex]
Using unitary method to find weight of [tex]x[/tex] horses.
If 1 horse weights = 1,200 lb
Then [tex]x[/tex] horses will weight in lbs = [tex]1,200\times x = 1,200x[/tex]
Total weight of horses and trailer in lbs = [tex]1200x+2700[/tex]
Since the maximum weight the truck can tow = 5,000 lb, so the inequality can be given as:
[tex]1200x+2700\leq5000[/tex]
Subtracting both sides by 2700.
[tex]1200x+2700-2700\leq5000-2700[/tex]
[tex]1200x\leq2300[/tex]
Dividing both sides by 1200.
[tex]\frac{1200x}{1200}\leq\frac{2300}{1200}[/tex]
[tex]x\leq1.91[/tex]
From the inequality solution for [tex]x[/tex], 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.
