Mrs. Siebenaller bought a bus for 25,000 with a 7% interest rate mrs s gets a loan payoff of 60 months how much interest would s

Artist 52 [7]

Answer:

$\$4701.80$

Step-by-step explanation:

Mrs. Siebenaller bought a bus for 25,000 with a 7% interest rate and she gets a loan payoff of 60 months,

We know that,

$\text{PV of annuity}=P\left[\dfrac{1-(1+r)^{-n}}{r}\right]$

Where,

PV = Present value of annuity = 25000,

r = rate of interest of each period = $\dfrac{7}{12}$ % monthly

n = number of periods = 60 months,

Putting the values,

$\Rightarrow 25000=P\left[\dfrac{1-(1+\frac{0.07}{12})^{-60}}{\frac{0.07}{12}}\right]$

$\Rightarrow P=\dfrac{25000}{\left[\dfrac{1-(1+\frac{0.07}{12})^{-60}}{\frac{0.07}{12}}\right]}$

$\Rightarrow P=\$495.03$

Hence total amount paid is,

$=495.03\times 60=\$29,701.80$

Therefore interest amount is,

$=29,701.80-25,000=\$4701.80$

in a sale, there is twenty-five per cent off all prices. a chair costs £45 in the sale how much was it before the sale

ryzh [129]

First, you need to know what is 25 percent of 45, so you do 45 times 25 divided by 100 and you are going to get 11.25. Then you take the 45 and subtract those 11.25, which will give you 33.75 because it's saying how much was it before the sale. That's your final answer.

How far, D, does a vehicle travel if it is moving at a rate, r, of 60 km/h and it travels for t =150 minutes? Use the formula D=

strojnjashka [21]

The distance of a vehicle travel is 150 km, at a moving rate of 60 km/h for 150 minutes.

Step-by-step explanation:

The given is,

Moving rate, r = 60 km/h

Time, t = 150 minutes

Step:1

We need to find the distance traveled by the vehicle,

From given the formula is

D = rt

Where,

D = Distance in Km

r = Moving rate in Km/h

t = Time in hours

Step:2

We need to convert the time minutes to hours

t = $\frac{150}{60}$ hours

t = 2.5 hours

Step:3

Distance traveled by the vehicle is,

D = 60 × 2.5

= 150

D = 150 Km

Result:

The distance traveled by the vehicle is 150 Km at a moving rate of 60 km/h for 150 minutes.

Determine the linear function for a graph that is a line with a slope of 1/7

VARVARA [1.3K]

The linear equation is y = (1/7)*x + 11/7.

<h3>How to get the linear equation?</h3>

The general linear equation is:

y = a*x + b

Where a is the slope.

Here we know that a = (1/7), then the line is:

y = (1/7)*x + b

We also know that the line contains the point (-4, 1), this means that when x = -4, we must have y = 1.

Replacing that, we get:

1 = (1/7)*(-4) + b

1 + 4/7 = b

7/7 + 4/7 = b

11/7 = b

So the linear equation is:

y = (1/7)*x + 11/7.
