Jon and Erin are purchasing a new TV and stereo surround system for their living room. The cost of both items is $1675.00. They are purchasing them with an installment loan that has an APR of 12%. The store financing requires a 10% down payment, and 12 monthly payments. A. Find the amount of the down payment. B. How much will they finance? C. Write an equation for the monthly payment. Use the chart below.
Answer:
$167.50
$1507.50
$134
Step-by-step explanation:
Given that:
Cost of sound system = 1675
APR, = 12%
Down payment = 10%
Number of monthly payments = 12
r = 0.12 / 12 = 0.01
Amount of down-payment :
10% * cost of sound system
0.1 * 1675 = $167.50
Amount to be financed :
$1675 - $167.50
= $1507.50
Monthly repayment :
Using the relation :
A / {[(1+r)^n]-1}/[r(1+r)^n]
1507.5 / (1+0.01)^12-1)/(0.01(1+0.01)^12)
1507.50 / 0.1268/(0.01 * 1.1268)
1507.50 ÷ (0.1268/0.01126)
1507.50 ÷ 11.25
= $134

What is the Fundamental Counting Theorem?The Fundamental Counting Theorem states that if there are n independent trials, each with [tex]n_1, n_2, \cdots, n_n[/tex] possible results, the total number of outcomes is calculated by the multiplication of the number of outcomes for each trial as presented as follows:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
For this problem, we have that the parameters are given as follows:
For each letter, there are 26 outcomes.For each of the first three digits, there are ten outcomds.For the last digit, there is only one outcome, which is of 5.Hence the total number of combinations is given as follows:
N = 26³ x 10³
N = 17,576,000

Four friends are playing a "Guess my Age" game. The come up with the following
clues. Dave's age is 15% of Sabrina. Luca's age is 75% of Sabrina and Rhianna is 300%
of Dave. The sum of their ages is 141. How old is Rhianna?
Show your work!
Answer:
27 years old
Step-by-step explanation:
What I know
Let D = Dave, S = Sabrina, etc. Then:
(1) [tex]D=0.15S[/tex]
(2) [tex]L=0.75S[/tex]
(3) [tex]R=3.00D[/tex]
(4) [tex]D+S+L+R=141[/tex]
Want to find R. Taking equation 3 and rewriting equation 4, we get
[tex]R=3.00D[/tex]
[tex]R=141-D-S-L[/tex]
So if [tex]R=R[/tex], then
[tex]3D=141-D-S-L-R[/tex]
[tex]4D=141-S-L[/tex] by adding [tex]D[/tex] to both sides.
Using equation 1 and equation 2, I can rewrite everything in terms of [tex]S[/tex] and get:
[tex]4(0.15S)=141-S-0.75S[/tex]
[tex]0.6S=141-1.75S[/tex]
[tex]2.35S=141[/tex] by adding [tex]1.75S[/tex] to both sides.
[tex]S=60[/tex] by dividing 2.35 both sides.
Now that I know Sabrina's age, I'll work towards getting Rhianna's using equation 1 and equation 3:
[tex]D=0.15(60)=9[/tex]
[tex]R=3.00(9)=27[/tex]
Checking my work:
Dave: 9
Sabrina: 60
Luca: 45 (since 9+60+45+27=141)
Rhianna: 27
9 is 15% of 60
45 is 75% of 60
27 is 300% of 9

A sweater is 15% off. The regular price is $24. What is the price after the discount is taken off?
Answer:
$20.40 after the discount
Step-by-step explanation:
To find 15% of 24, you multiply 24 and 0.15, which gets you 3.6
Then, to find the price after the discount, you subtract the 15% (the 3.6). So, 24 - 3.6 = $20.40

Find the missing angle
Answer:
c = 32
Step-by-step explanation:
90 + 58 + c = 180
90 + 58 = 148
180 - 148 = 32
c = 32
Answer:
32
Step-by-step explanation:
As we know the total degree of a triangle is 180 degrees.
In this triangle so far we have a 58 degree and 90 degree box since its a right triangle so we have to take:
58 + 90 = 148
After taking 148 we have to subtract the 180 to find the missing number that will help us complete everything:
180 - 148 = 32

Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures cell phones, can be modeled by the polynomial 2x2 + 55x + 10. The cost, in dollars, of producing the cell phones can be modeled by 2x2 – 15x – 40. The variable x represents the number of cell phones sold.
What expression represents the profit, and what is the profit if 240 cell phones are sold?
40x – 30; $2,400
40x – 30; $9,570
70x + 50; $16, 850
70x + 50; $28,800
Answer:
Given that the equation of the revenue is R=2x2+55x+10 and the equation of the cost is C=2x2 – 15x – 40, you will get the profit by subtracting the revenue from the cost: R-C=P. Therefore, P=(2x2+55x+10)-(2x2 – 15x – 40). You will get P=70x+50 where x is is the number of cellphones sold. If 240 cellphones are sold, then the profit is 16850 dollars.
Step-by-step explanation:
The profit expression is 70x + 50 and the profit if 240 cell phones are sold is $16,850
How to calculate profitRevenue, R = 2x² + 55x + 10Cost, C = 2x² – 15x – 40where,
x = number of cell phones sold.
Profit = Revenue - cost
= (2x² + 55x + 10) - (2x² – 15x – 40)
= 2x² + 55x + 10 - 2x² + 15x + 40
Profit = 70x + 50
If x = 240Profit = 70x + 50
= 70(240) + 50
= 16,800 + 50
= $16,850

y=3x+2
Step-by-step explanation:
slope= rise/run
rise=3 run=1 slope=3
y intercept is 2
y=3x+2
Answer:
y = 3x + 2
Step-by-step explanation:
(1, 5) and (2, 8)
Slope:
m=(y2-y1)/(x2-x1)
m=(8-5)/(2-1)
m=3/1
m=3
y - y1 = m(x - x1)
y - 5 = 3(x - 1)
y - 5 = 3x - 3

Answer:
(x, y) ⇒ (x -5, y +3)
Step-by-step explanation:
Pick a point on the original polygon. The extreme left point (at (1, 0)) will do.
Locate the corresponding image point on ABCDE. (It is point B(-4, 3).) Using coordinates, or counting grid squares, determine what must be added to the original point to get the image point.
Here, that addition is 5 squares left and 3 squares up:
image - original = (-4, 3) -(1, 0) = (-5, 0)
So, the transformation rule adds -5 to each x-coordinate and 3 to each y-coordinate:
(x, y) ⇒ (x -5, y +3)

I walk to the bike shop at 3 miles per hour and cycle back along the same route at 12 miles per hour. What is my average speed, in miles per hour, for the time I am actually travelling on the route?
Answer: 7.5 miles per hour
Step-by-step explanation:
First speed was 3 miles per hour.
Second speed was 12 miles per hour.
To do an average, add both speeds and divide by two, which is the number of trips made.
= (3 + 12) / 2
= 15 / 2
= 7.5 miles per hour
