Cosxtanx - 2cox^2x = -1

given inequality is : 1200x < 50000

the correct word problem will be : a) an export company needs to purchase containers to ship cargo overseas, and the expense must be less than $50,000. if 41 containers are purchased, what is the cost of each container?  

here, lets suppose the rate of each container be 1200 and x is the number of containers purchased which is 41.

so when 41 containers are purchased, it means the cost will be which is less than 50000.
