B?

xapproachesinfinity · Answer

for year 7 the cost is roughly around 1500$
for year 1 the cost is by my best estimate 4560
so 1500-4560=-3060
take that and divide it by number of year between them 7-1=6

3000/6=500
10/6=10
so 510
i would go with the first choice -550
since i got -510 using my estimate numbers
