Given: \(3(x – 7) \geq 9\)
Divide both sides of the inequality by \(3\) to get: \(x – 7 \geq 3\)
Add \(7\) to both sides to get: \(x \geq 10\)

Also given: \(0.25y – 3 \leq 1\)
Add \(3\) to both sides to get: \(0.25y \leq 4\)
Multiply both sides by \(4\) to get: \(y \leq 16\)

We now know that \(x \geq 10\) and \(y \leq 16\)
So, for example, it could be the case that x = 12 and y = 12, in which case the two quantities are equal
Or, it could be the case that x = 13 and y = 12, in which case Quantity A is greater

Answer: D

Cheers,
Brent
