Solve the system.

Alex777 [14]

Answer:

{x,y,z} = {-18,4,2}

Step-by-step explanation:

Solve equation [2] for the variable x

x = -10y + 2z + 18

Plug this in for variable x in equation [1]

(-10y+2z+18) + 9y + z = 20

- y + 3z = 2

Plug this in for variable x in equation [3]

3•(-10y+2z+18) + 27y + 2z = 58

- 3y + 8z = 4

Solve equation [1] for the variable y

y = 3z - 2

Plug this in for variable y in equation [3]

- 3•(3z-2) + 8z = 4

- z = -2

Solve equation [3] for the variable z

z = 2

By now we know this much :

x = -10y+2z+18

y = 3z-2

z = 2

Use the z value to solve for y

y = 3(2)-2 = 4

Use the y and z values to solve for x

x = -10(4)+2(2)+18 = -18

You want to purchase an automobile for $ 26 comma 706. The dealer offers you 0% financing for 60 months or a $ 3 comma 926 reba

Alexxandr [17]

Answer:

Since the monthly payment with rebate is lower than monthly payment for 0% financing, I will choose the $3,926 rebate

Step-by-step explanation:

Price of the automobile = $26,706

There is 0% financing for 60 months

Rate = 6.3%

Monthly payment for 0% financing = 26706 ÷ 60 = $445.1

Rebate = $3,926

Monthly payment for $3926 rebate

Formula for calculating present value ( PV) for Annuity payment

$P = \frac{r * PV}{1 - (1+r)^{-n} }$ ...................(1)

P = monthly payment

r = Rate per period = 6.3%/12

r =(6.3/100)/12 = 6.3/1200

r = 0.00525

Present value, PV = 26706 - 3926 = $22780

number of payments, n = 60

Substituting these values into the equation (1) above

$P = \frac{0.00525 * 22780}{1 - (1+0.00525)^{-60} }$

P = $443.59

Note : From calculations, Monthly payment with rebate = $443.59, while monthly payment for 0% financing = $445.1

Since the monthly payment with rebate is lower than monthly payment for 0% financing, I will choose the $3,926 rebate
