Noel Devine bought a new dishwasher for $320. He paid $20 down and made 10 monthly payments of $34. What actual yearly interest rate did Noel pay? A. 29.09% B. 68.75% C. 14.55% D. 34.38%I know I'm making this harder than it needs to be, but I really don't understan. Can you please explain how to get the answer? Thanks!!!

Answers

Answer: option C. 14.55%

Explanation:

1) Total payments done:

Down payment + 10×montly payments = $20 + 10×$34 = $20 + $340 = $360

2) Interest paid

Total payments - original price = $360 - $320 = $40

3) Financed amount

Original price - down payment = $320 - $20 = $300

3) Percent interest

(Interest paid / financed amount ) × 100 = ($40 / $300) × 100 = 13.33%

4) Yearly rate

number of months in a year: 12

number of months to pay: 10 + 1 = 11

⇒ (Percent interest / 11) × 12 = (13.33% / 11) × 12 = 14.54%

Note that it has been assumed that the first monthly payment was made one month after the purchase, which leads to a total payment time of 11 months, that is why the divisor (denominator of the fraction is 11 and not 10).

IN finding the interest we need to use the following formula:
Interest= Principal x Rate x Time or I= PRT
Substitute values: I= [$20 + ($10 x $34)] -320 =$40
P= $320
R=?
T=10 months/year
I=PRT
Since R is a missing term, we will solve for R using this formula: R=I/PT
R= [$20 + ($10 x $34)-320] / ($320 x 10 months)
T=10 months÷12 months=0.83
R= ($40)/ $320 X 0.83
R= 40/ 265.6
R=15.06024096

For $7.52, you purchased 8 pens and highlighters from a local bookstore. Each highlighter costs $1.09 and each pen costs $.69. How many pens did you buy.

Answers

p=number of pens
h=number of highlighters

p+h=8

1.09h+0.69p=752

p+h=8
minus h from both sides
p=8-h

sub that for p

1.09h+0.69(8-h)=7.52
1.09h+5.52-0.69h=7.52
0.4h+5.52=7.52
minus 5.52 from both sides
0.4h=2
divide both sides by 0.4
h=5

sub back

h=8-p
5=8-p
minus 8 frm both sides
-3=-p
mltiply both sides by -1
3=p

3 pens you bought

Let p be the number of pens purchased and h be the number of highlighters purchased.
p + h = 8 ..........(1)
h = 8 - p ...........(2)
0.69p + 1.09h = 7.52 ........(3)
Plugging the value for h from (2) into equation (3) we get:
0.69p + 1.09(8 - p) = 7.52 .....(4)
Expanding the bracket in (4) gives:
0.69p + 8.72 - 1.09p = 7.52
Therefore
-0.4p = -1.2
p = -1.2/-0.4 = 3
The answer is 3 pens.

Meg pounded a stake into the ground. When sheattached a leash to both the stake and her dog’s collar,
the dog could reach 9 feet from the stake in any direction.
Using 3.14 for π, what is the approximate area of
the lawn, in square feet, the dog could reach from the
stake?

Answers

The area of the lawn that the dog can reach from the stake is 254.34 square feet.

What is the area?

The measurement that indicates the size of a region on a plane or curved surface is called the area. Surface area refers to the area of an open surface or the border of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

Given that, the dog can reach 9 feet from the stake in any direction.

Therefore, the area that the dog can cover is a circle with a radius of 9 feet.

The area of the circle is:

A =π(9)²

A = 3.14 × 81

A = 254.34

Hence, the area of the lawn that the dog can reach from the stake is 254.34 square feet.

The dog is able to run around in a circle with a radius of9 ft.

The area of a circle is A = pi r^2

A = (3.14) (9)^2
A= (3.14)(81)
A= 254.34 sq ft

A shipping company charges 15 to ship a package and 5% of the shipping charge for insurance on the package what is the total cost to ship this particular itema $90.00
b 15.75

Answers

The total cost of shipping a package with the cost of $15 exclusive if 5% insurance is 15.75 dollars. This is calculate by getting first the 5% of 15 dollars, 15 dollars multiplied by 5%, equal to 0.75 dollars. Then it will be added to the shipping cost of 15, which is equal to 15.75 dollars.
