Answer

Explanation:

Step1: Identify two points

Use points $(2, 480)$ and $(5, 150)$

Step2: Calculate total fund decrease

$\text{Total decrease} = 480 - 150 = 330$

Step3: Calculate number of desks added

$\text{Desks added} = 5 - 2 = 3$

Step4: Find per-desk decrease

$\text{Per-desk decrease} = \frac{330}{3} = 110$

Answer:

A. $110
