Which inequality statement describes the two numbers on a number line?
6 and a number 10 units to the left of 6

The answer is 25,200.
This can be solved by using proportion.
Set up the proportion as follows:
 (10,800/30,000)=(x)/(70,000)
By cross multiplying you get:
 (30,000)(x)=(70,000)(10,800)
               x=[(70,000)(10,800)]/30,000
               x=25,200 coats
