Yusuf is taken a trip on the airplane. He knows that to avoid extra fees. His suitcase must weigh under 50 pounds. The suitcase with his clothes weighs 35 pounds. He has rooms, so he decides to pack some boots for his trip to each book, weighs on average 1.2 pounds. How many boots could he bring on the trip

To find out how many boots Yusuf can bring on the trip, we need to subtract the weight of his clothes from the weight limit for the suitcase: 50 pounds - 35 pounds = 15 pounds.

Since each boot weighs 1.2 pounds, we can find the number of boots by dividing the weight limit by the weight of each boot: 15 pounds / 1.2 pounds/boot = 12.5 boots.
Since Yusuf cannot bring a fraction of a boot, he can bring a maximum of 12 boots on the trip.
