show the algebraic inequality

Question

The profit for a company is determined by the equation y = 0.02x – 0.30, where y represents the profit and x represents the number of items sold. How many items must be sold so that the profit will be at least $4000?

Answer 1

I suspect you have a typo but
solve equality first. Any greater number sold gives more profit.
4000 + .3 = .02x
x = 200,000
so
x>200,000

Answer 2

thank you, that is actually how the word problem was phrased.
