D = 0.7857 g/cm³
V = 28.58 mL
m = ?
d = m / V
m = d · V
V = 28.58 mL = 28.58 cm³
m = 0.7857 g/cm³ · 28.58 cm³
m = 22.4553 g

swat32

Answer:

Total purchase = $28498.685

In cent = 2849868.5 cent.

Step-by-step explanation:

Given : You have decided to purchase a car for 175.13.

To find : What is the total purchase price of the car including tax, license, and title?

Solution :

Price of car = $25,625

Sales tax = 7.5% = 0.075

The total purchase price of the car including tax is

T=25625\times 0.075=\$1921.875T=25625×0.075=$1921.875

Title charges are $175.13.

The credit union requires a 10% down payment and will finance the balance with a 9% annual interest loan for 36 months.

10% down payment on price of car

25625\times 0.10=2562.525625×0.10=2562.5

25625-2562.5=23062.525625−2562.5=23062.5

The amount will be $23062.5

Now, we find the monthly payment,

Monthly payment, M=\frac{\text{Amount}}{\text{Discount factor}}M=

i=\frac{0.09}{12}=0.0075i=

Time n=36 month

Now, put all the values we get,

D=\frac{1-(1+i)^{-n}}{i}D=

​

D=\frac{1-(1+0.0075)^{-36}}{0.0075}D=

D=\frac{1-(1.0075)^{-36}}{0.0075}D=

1−(1.0075)

​

D=\frac{0.2358}{0.0075}D=

0.2358

​

D=31.44D=31.44

Monthly payment, M=\frac{\text{Amount}}{\text{Discount factor}}M=

Amount

​

M=\frac{23062.5}{31.44}M=

23062.5

​

M=733.38M=733.38

Monthly payment is $733.38

For 36 months the payment is 733.38\times 36=26401.68733.38×36=26401.68

Licence = $26401.68

The total purchase price of the car including tax, license, and title

Total purchase = 1921.875 +1921.875+175.13 +$26401.68

Total purchase = $28498.685

1 dollar = 100 cent

$28498.685 = 2849868.5 cent.
