Christina bought a car that cost $18000. She put $4000 down and financed the rest at 3.8%/a compounded monthly. She wants to pay

skelet666 [1.2K]

Christina's monthly payment is $583

Her total interest payment is $584

What does monthly compounding mean?

Monthly compounding means that the interest on the loan is computed every month, it shows the frequency of interest computation during the loan tenure.

In this case, the monthly payment can be determined using the present value formula of an ordinary annuity since the monthly payment would occur at the end of each month.

PV=PMT*(1-(1+r)^-N/r

PV=loan amount=cost of car-down payment

PV=$18,000-$4,000

PV=$14,000

PMT=monthly payment=unknown

r=monthly interest rate=3.8%/12=0.003166666666666670

N=number of monthly payments=25

$14,000=PMT*(1-(1+0.00316666666666667)^-25/0.003166666666666670

$14,000=PMT*(1-(1.00316666666666667)^-25/0.003166666666666670

$14,000=PMT*(1-0.924001500485879000)/0.003166666666666670

$14,000=PMT*0.075998499514121000/0.003166666666666670

PMT=$14,000/0.075998499514121000*0.003166666666666670

PMT=$583.34

PMT=$583( nearest dollar)

The total interest is the total 25 monthly payments minus the loan amount

total interest=( $583.34*25)-$14,000

total interest=$583.50

total interest=$584

Whats the solution to the system of inequalities? -3x-y+z=6 -3x-y+3z=0 -3z=3

Naya [18.7K]

Answer:

This system of equations has no solution. It is inconsistent.

Step-by-step explanation:

The last equation tells you z = -1.

Substituting this value for z in the other two equations allows them to be written as ...

-3x -y = 7

-3x -y = 3

There are no values of x and y that can make both these equations true.

Elizabeth swims 50 feet in ten seconds. Jesse swims 110 feet in 20 seconds. Reagan swims 160 feet in half a minute. Who swims fa

qwelly [4]

Answer:

The Jesse swim fastest

Step-by-step explanation:

Given as :

The distance cover by Elizabeth while swimming = 50 feet

The time taken by Elizabeth = 10 sec

So, Speed of Elizabeth = $\frac{Distance}{Time}$

∴ Speed of Elizabeth = $\frac{50}{10}$ = 5 feet per sec

Again ,

The distance cover by Jesse while swimming = 110 feet

The time taken by Jesse = 20 sec

So, Speed of Jesse = $\frac{Distance}{Time}$

∴ Speed of Jesse = $\frac{110}{20}$ = 5.5 feet per sec

Again ,

The distance cover by Reagan while swimming = 160 feet

The time taken by Reagan = 30 sec

So, Speed of Reagan = $\frac{Distance}{Time}$

∴ Speed of Reagan = $\frac{160}{30}$ = 5.3 feet per sec

So, $Speed of Elizabeth< Speed of Reagan < Speed of Jesse$

Hence The Jesse swim fastest Answer
