Suppose that you borrow $15,000 for five years at 8% toward the purchase of a car. find the monthly payments and the total interest for the loan. the monthly payment is? the total interest for the loan is?

Step-by-step explanation:

Using the time-value-of-money functions on your calculator, you can find the monthly payment to be $304.15.

The calculator function requires several inputs. There are 12 payments per year for 5 years, for a total of 60 monthly payments. As the problem statement tells you, the present value is 15,000, the interest rate is 8%. You want the remaining amount due after 5 years (the future value) to be zero. There are 12 payments per year, and interest is compounded 12 times per year.

After finding the monthly payment, you can find the total amount repaid by multiplying it by 60 (the number of months). Then the interest paid is the difference between that ($18249.00) and the initial loan amount ($15,000.00).

... $18,249 -15,000 = $3,249.00

The attachment shows what these calculations look like on a TI-84 calculator.

a.   we have two

lines:   y = 4-x   and  

y = 8-x^-1

given two simultaneous equations that are both to be

true, then the solution is the points where the lines cross. the intersection is

where the two equations are equal. therefore the solution that works for both

equations is when

4-x = 8-x^-1

this is where the two lines will cross and that is the

common point that satisfies both equations.

b.   4-x = 8-x^-1

  x           4-x       8-x^-1

-3           7        

8.33

-2           6         8.5

-1           5         9

  0           4        

-

  1           3        

7

  2           2        

7.5

  3           1         7.67

the table shows that none of the x values from -3 to 3 is

the solution because in no case does

4-x = 8-x^-1

to find the solution we need to rearrange the equation to

find for x:

4-x = 8-x^-1

multiply both sides with x:

4x-x^2 = 8x-1

x^2+4x-1=0

x= -4.236, 0.236

therefore there are two points that satisfies the

equation.

find y:  

x=-4.236

y = 4-x   = 4 – (-4.236)

= 8.236

y = 8-x^-1 =   .236)^-1

= 8.236

x=0.236

  y = 4-x   = 4 – (0.236) = 3.764

y = 8-x^-1 =   8-(0.236)^-1

= 3.764

thus the two lines cross at 2 points:

(-4.236, 8.236) & (0.236, 3.764)

c.   to solve

graphically the equation 4-x = 8-x^-1

we would graph both lines: y = 4-x   and   y

= 8-x^-1

the point on the graph where the lines cross is the

solution to the system of equations.

just graph the points on part b on a cartesian coordinate

system and extend the two lines.   the

solution is, as stated, the point where the two lines cross on the graph.
