The inequality would be 50w + 100 >_ 18,000 ( the _ goes under the > but I cannot do that on my phone )
The hundredth is the second number to the right of the decimal point. Also, if the number directly to the right of it is 5 or larger, you will have to round up by one.
23.558 becomes 23.56.
0.39x ≤ 5.85 . . . . . . one way to write the inequality
The correct answer in my opinion is 2x+3y= -6 <span />
