Answer:
The system of inequalities would be:
L+M >= 500 (greater than or equal to)
2L + 0.5M <= 850 (less than or equal to)
The first inequality deals with the total number of balloons. She wants the total to be at least 500, so add the variables and set it greater than or equal to 500.
The second inequality deals with the helium. 2L comes from each latex balloon using 2 ft^3 of helium. 0.5M comes from each Mylar balloon using 0.5 ft^3. Together they can use no more than 85% of the 1000 ft^3 tank; 85% = 0.85; 0.85×1000=850. "No more than" tells us it must be less than or equal to

For number 15 it is 66,000
Lets see: 36 cookies is 12% of the total order, so 36/12=3 1% of the order, and so there are 3*100=300 total cookies in the order.
So 300 is your answer.
