Develop a word problem (within the context of your topic) that demonstrates the use of an inequality
(ex: During the years 1989-2015, Chinas suicide rate was on the rise then fell down and platued...) *find when the graph is less than 50 to better fit the graph*
(random example: In the 20th century Kuwait underwent a destructive war with Iraq where thousands of male soldiers aged 20-34 died. The kuwait government wants to find what year the male population aged 20-34 went under 45% so they so can study the data and find how destructive the war was.)
Solve the inequality graphically, using www.desmos.com for assistance and express your solution in both set and interval notation. (You must include the desmos link in your work as well)
