So you want to finance a car for $4840 let's say we offer a 4.5% interest rate on a two year loan at 6% on a five year loan?
Virty [35]

Answer:

Interest Rate on 2-Year Loan...$435.6

Interest Rate on 5-Year Loan...$1,452

Step-by-step explanation:

The formula for calculating simple interest is as follows.

I = P x R x T,

where I = interest

P= Principal

R= interest rate

T= time

For the loan at 4.5 percent for 2 years, the interest will be

=  $4,840 x 4.5/100 x 2

= $4,840 x 0.045 x 2

= $435.6

Total cost of the loan will principal plus interest

=$435.6 + $4,840

=$5,275.6

Monthly loan cost

= $5,275.6/24

=$219.81

Total loan cost..$5,275.6

Monthly loan cost ...$219.81

For the Loan at 6 percent for 5 years, the interest will be

= $4,840 x 6/100 x 5

= $4,840 x 0.06 x 5

=$1,452

Total cost of the loan will be principal plus interest

=$ 4,840 + $1,45

=$6,292

Monthly costs will be

=$6,292/60

=$104.87

Total loan cost... $6,292

Monthly loan  costs... $104.87

QUICK!! 18x^2+21x-60=0 pls give me the steps as well
Anton [14]

Answer:

<h2>x1 =  -  \frac{5}{2}</h2>

x2 =  \frac{4}{3}

Step-by-step explanation:

18 {x}^{2}  + 21x - 60 = 0

Divide both sides of the equation by 3

6 {x}^{2}  + 7x - 20 = 0

Write 7x as a difference

6 {x}^{2}  + 15x - 8x - 20 = 0

Factor out 3x from the expression

3x(2x + 5) - 8x - 20 = 0

Factor out -4 from the expression

3x(2x + 5) - 4(2x + 5) = 0

Factor out 2x + 5 from the expression

(2x + 5)(3x - 4) = 0

When the product of factors equals 0 , at least one factor is 0

2x + 5 = 0

3x - 4 = 0

Solve the equation for X

2x + 5 = 0

Move constant to R.H.S and change its sign

2x = 0 - 5

Calculate the difference

2x  =  - 5

Divide both sides of the equation by 2

\frac{2x}{2}  =  \frac{ - 5}{2}

Calculate

x 1=  -  \frac{5}{2}

Again,

3x - 4 = 0

Move constant to RHS and change its sign

3x = 0 + 4

Calculate the sum

3x = 4

divide both sides of the equation by 3

\frac{3x}{3}  =  \frac{4}{3}

Calculate

x 2=  \frac{4}{3}

Hope this helps..

Best regards!!
