suppose you are the financial manager of the International Emirates University IEU. And you are requested at the end of the year
2020 to pay 30,000 as the building rent for the coming two years. Furthermore at the end of the year 2022 you are requested to renew the university working licenses with total amount of $ 50,000 for the coming two years. Also, at the end of the year 2023 you have to face withdraw of $80,000 to pay well-known fees to the head of university in Dubai. If you can earn 8% in your fund how much you should deposit by today to reach your goals, and to leave your balance zero after the last withdrawal?
so compound first thing till 2020, take out 30000 the remaining is copmpounded til 2022, take out 50000 remaining is compounded for 1 more year and that is equal to 80000
so from 2017 to 2020, that is 5 years from 2020 to 2022 is 2 years from 2022 to 2023 is 1 year
work backwards
A=P(r+1)^t last one A=80000 P=? r=0.08 t=1 year
80000=P(1.08)^1 divide both sides by 1.08 I would leave in fraction 20000000/27=P
now that is the remaining after paying 50000, after 2 years of compounding
so 50000+(2000000/27)=P(1.08)^2 solve using math about 106374=P
now reverse back
5 years paid 30000
30000+106374=P(1.08)^5 solve using math 92813.526=P round $92813.53
Perpendicular lines have slopes that are negative reciprocals. example: line a has a slope of 2/3, line b has a slope if -3/2 if they are perpendicular.
