After many sunset viewings at SUNY Brockport, Amanda dreams of owning a waterfront home on Lake Ontario. She finds her perfect house listed at $425,000. Leveraging the negotiation skills she developed at school, she persuades the seller to drop the price to $405,000. What would be her annual payment if she opts for a 30-year mortgage from Five Star Bank with an interest rate of 14.95% and no down payment? a- $25,938 b- $26,196 c- $24,500 d- $27,000

Imagine that the SUNY Brockport Student Government Association (SGA) is considering investing in sustainable campus improvements. These improvements include installing solar panels, updating campus lighting to energy-efficient LEDs, and implementing a rainwater collection system for irrigation. The total initial investment required for these projects is $100,000. The projects are expected to generate savings (effectively, the cash inflows in this scenario) of $30,000 in the first year, $40,000 in the second year, $50,000 in the third year, and $60,000 in the fourth year due to reduced energy and maintenance costs. SUNY Brockport’s discount rate is 8%. What is the NPV of the sustainable campus improvements? (rounded) a- $70,213b- $48,729c- $45,865d- $62,040
