youssef is taking a trip on an airplane. he knows that to avoid extra fees his suitcase must weight under 50 pounds. the suitcase with his clothes weighs 35 pounds. he has room, so he decides to pack some books for his trip, too, each book weighs on average 1.2 pounds. how amny books could he bring kn the trip? he writes the inequality 1.2b + 35 < 50 where b equals the number of books. to help figure this out, solve his inequality. use the letter b as your variable and write your b term first
The inequality can be written as:
1.2b + 35 < 50
To solve the inequality for b:
1.2b < 50 - 35
1.2b < 15
Next, divide both sides of the inequality by 1.2 to isolate the b variable:
b < 15 / 1.2
b < 12.5
Therefore, Youssef can bring a maximum of 12 books on his trip.
