Hi, now we are going to calculate the total cost and total interest.
00:05
Now in the first question the given cost is $3 ,715 and the down payment is $800 and t is equal to 2 s or is equal to 5 percentage that is 0 .05.
00:32
5 now we know that the formula for calculating the amount a is equal to p into 1 plus r t for that now we have to find p p is nothing but cost minus down payment so it will be equal to 3 ,715 minus 800 that is 2 ,915 dollar and then substitute the corresponding values in the above formula then we have a is equal to 2 ,915 into 1 plus 0 .05 into 2 and it will be equal to $3 ,206 .5 then we have the total cost is equal to 3 ,206 .5 plus 800 and it will be equal to 4 ,06 .6 .5 plus 800 and it will be equal to 4 ,06.
01:38
And the total interest is equal to 4 ,065 minus 3 ,715 and it will be equal to $291 .5.
01:58
Now in the second question, the given cost is equal to $3 ,755 and the down payment is equal to $1 ,000, t is equal to 4 years or is equal to 7 percentage.
02:13
That is 0 .07.
02:15
So now we have p is equal to 3 ,755 minus thousand.
02:23
And it will be equal to $2 ,750 .5.
02:28
And next, substitute the corresponding values for calculating the amount...
