18+36=54
i tried to do all of these and none of them add up to 54
The answer is 44 and if he deposits it is 33 dollars:
11x4
1x4=4
1x4=4
So 11x4=44
And if he deposits 11 he will have 33
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -15 ± √((15)^2 - 4(2)(4)) ] / ( 2(2) )
x = [-15 ± √(225 - (32) ) ] / ( 4 )
x = [-15 ± √(193) ] / ( 4)
x = [-15 ± sqrt(193) ] / ( 4 )
x = -15/4 ± sqrt(193)/4
The answers are -15/4 + sqrt(193)/4 and -15/4 - sqrt(193)/4.
Answer:
Ans. you should deposit each month to end up with $38,000 the amount of $533.33 every month for 5 years at a APR of 6.5%
Step-by-step explanation:
Hi, first we have to convert all the data to monthly basis, that is, 5 years (5*12=60 months) and the rate of 6.5% APR offered by the bank (Monthly rate = 0.065/12=0,005666667 or 0.5667% monthly)
With that in mind, we need to solve for "A" the following equation.
Where:
FV = Future value of the car
r = rate of return offered by the bank
n = number of periods that you are going to make the monthly deposit
That is:
Best of luck.
