Miss. Mulán wants to have money available for two trips he wants to make within two (2) and (four) 4 years respectively. For the first trip (year 2), it will require $ 50,000 MN and for the second (year 4) of $ 65,000 MN. Therefore he knows that he must save. The bank that offers the best interest rate is the ACME bank with an annual compound interest rate of 4.5%. How much should you deposit today in order to have the amounts you want in the years that your trips are scheduled?
To solve this question , we must know that
If an amound A is deposited
Annual compound intrest = R%.
Then , Amount he would have at the end of n years =
We need an amound of $50,000 in 2 years , $ 65,000 in 4 years.
we will find the principal amount required for both the trips seperately and add them to get the total amount he needs to deposit in the bank.
First Trip :-
Let , A1 be the amound deposited.
Rate of intrest = 4.5%.
Number of years = 2.
We need to find the amount A1 that has to be invested in the bank , so that we get $50,000 after 2 years.
So , $50,000 =
From the above equation , A1 =
= $ 45,786.49756
Second Trip :-
Let A2 be the amount deposited.
Rate of Intrest = 4.5%
Number of Years = 4.
We are trying to find the amount A2 that has to be invested , so that we can afford the second trip.
SO , $65,000 =
From the above equation , A2 =
= $ 54,506.48733
The Total amount A that has to be deposited ,so that Miss.Mulan can go for both the trips = A1 + A2
A = A1 + A2
= 45,786.49756 + 54,506.48733
= $ 100,292.9849
SOo , $100,292.9849 should be deposited today to have the amounts required for both the trips.
I hope that , it helps.If you have any queries regarding the solution , put it in the comments . I will modify / edit the answer according to your needs. Have a nice day :)
