Answer:
2K + 12L ≥ 87 and 1.5K + 8L > 63
Explanation:
It takes 2 wooden sticks and 1.5 square feet of paper to make a kite, and it takes 12 wooden sticks and 8 square feet of paper to make a lamp.
If K denotes the number of kites that Min-Young made and L denotes the number of lamps she made then
2K + 12L is the number of wooden sticks that she used which is greater than equal to 87
i.e. 2K + 12L ≥ 87 ........ (1)
Again, 1.5K + 8L is the number of square feet of paper that she used which is greater than 63 sq. feet
i.e. 1.5K + 8L > 63 ........... (2)
Hence, inequalities (1) and (2) are the required answer. (Answer)
