Answer:
D:  3(x + 5)(x + 5)
Step-by-step explanation:
Try multiplying the last answer choice (D); the result is 3(x^2 + 10x + 25), or
3(x + 5)(x + 5).
 
        
             
        
        
        
Equation: 99 + 45x, with x as how many ever months.
After five months: 
99 + 45(5) = 99 + 225 = $324.
