Cost of public colleges. the average cost, in dollars, for tuition and fees for in-state students at four- year public colleges over the period 2000-2014 can be modeled by the equation y = 4.065x2 + 370.1x + 3450 where x = 0 corresponds to 2000, x = 1 corresponds to 2001, and so on. based on this model, for what year after 2000 was the average cost $8605?

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
