Question 1182102
<br>
In my opinion, the given statement can be interpreted to mean two different ways, leading to inequalities that say  the exactly opposite things.<br>
(1) Strict mathematical interpretation....<br>
x = costs
y = revenue
y-29000 = $29,000 under revenues<br>
"A at least B" means A is greater than or equal to B:
"costs are at least $29,000 under revenues"  -->  x is greater than or equal to y-29000  -->  x >= y-29000 [1]<br>
(2) interpreting the English phrase....<br>
"costs are at least $29,000 under revenue"  -->  "the difference between costs and revenue is at least $29,000"<br>
y-x >= 29000 [2]<br>
Inequality [2] says the difference between revenue and costs is greater than or equal to $29000.<br>
But writing inequality [1] as revenue in terms of cost...<br>
x >= y-29000
x+29000 >= y
y <= x+29000
y-x <= 29000<br>
That says the difference between revenue and costs is LESS THAN or equal to $29,000.<br>
Since two valid interpretations of the given statement lead to opposite answers, the conclusion to be drawn is that the wording of the statement is deficient.<br>
