Dave grows wheat \((w)\) and barley \((b)\) on a farm. Dave expects to profit \(\$ 150\) per acre for wheat and \(\$ 180\) per acre for barley. The cost of raising each crop is \(\$ 30\) per acre for wheat and \(\$ 25\) per acre for barley. Dave budgets \(\$ 1,635\) for the raising of both crops. What is the constraint inequality in this situation?

a. \(150 w+180 b \leq 1,635\)

b. \(25 w+30 b \leq 1,635\)

c. \(w+b \leq 1,635\)

d. \(30 w+25 b \leq 1,635\)
