Higher interest rates won’t cost you as much to drive a car as do higher gasoline prices. This is because automobile loans have payment schedules that are only modestly impacted by Federal Reserve Board interest-rate increases. Create a spreadsheet to compare the difference in monthly payments for a K552,451 loan having 60 monthly payments for a select number of interest rates. Use 3% as the base APR and go as high as an APR of 12%.

First, think of what you know. you know that the number t the end of the equation will need to be subtracted because it is the money he lost from buying the lawn mower. and your first two weeks have negative profit, so that tells you that c and d are wrong. now you can plug any of the weeks into a and b to see which one works. i'll start with plugging week 1 into a.this isn't right because it says your answer for week one should be -90.so now we need to try the same thing with b.this one got you the right answer, (sometimes if you only check with one of the weeks multiple will work so you need to check with more of the weeks, but it worked out fine here)this means that b is the correct answer.let me know if you need more clarification. i hope this : )
