Answer:
The correct option is a.
Step-by-step explanation:
It is given that Nell's mortgage is $50,150 at 10 percent for 30 years and she must pay $8.78 points per $1,000.
EMI on $1000 is $8.78, so EMI on $1 is
[tex]\text{EMI on }\$1=\frac{8.78}{1000}=0.00878[/tex]
EMI on $50150 is
[tex]\text{EMI on }\$50150=0.00878\times 50150=440.317\approx 440.32[/tex]
Therefore the correct option is a.
