105/200 = 0.525
0.525 x 100 (to get the percent) = 52.5%
Answer:
52.5%
Step-by-step explanation:
Add together the number of papers delivered on Saturday and Sunday. Then divide that by the total number of papers delivered.
55+50 = 105
105/200=52.5%

Alana is purchasing a $160,000 home and her bank is offering her a 30-year
mortgage at a 4.9% interest rate. In order to lower her monthly payment,
Alana will make a 20% down payment and is considering a purchase of 3
points. How much lower will her monthly payment be if she purchases the
points?
Answer:
The amount by which her monthly payment will be lower if she purchases the points is $57.12.
Step-by-step explanation:
Since Alana will make a 20% down payment, the mortgage loan balance can be calculated as follows:
Mortgage loan balance = Mortgage amount – Down payment = $160,000 – ($160,000 * 20%) = $160,000 - $32,000 = $128,000
The amount by which her monthly payment will be lower if she purchases the points can now be calculated using the following steps:
Step 1: Calculation of monthly payment without purchasing 3 points
The monthly payment can be calculated using the formula for calculating loan amortization as follows:
P = (A * (r * (1 + r)^n)) / (((1+r)^n) - 1) .................................... (1)
Where,
P = monthly payment without purchasing 3 points = ?
A = Mortgage loan balance = $128,000
r = monthly interest rate = 4.9% / 12 = 0.049 / 12 = 0.00408333333333333
n = number of payment months = 30 years * 12 months = 360
Substituting all the figures into equation (1), we have:
P = ($128,000 * (0.00408333333333333 * (1 + 0.00408333333333333)^360)) / (((1 + 0.00408333333333333)^360) - 1)
P = $679.33
Step 2: Calculation of monthly payment if she purchases 3 points
Typically, each points purchased reduces the interest rate by 0.25%. Since Alana is considering a purchase of 3 points, her new interest rate can then be calculated as follows:
New interest rate = 4.9% - (0.25% * 3) = 4.9% - 0.75% = 4.15%
The monthly payment can also be calculated using the formula for calculating loan amortization as follows:
P3 = (A * (r * (1 + r)^n)) / (((1+r)^n) - 1) .................................... (2)
Where,
P3 = monthly payment if 3 points is purchased = ?
A = Mortgage loan balance = $128,000
r = new monthly interest rate = 4.15% / 12 = 0.0415 / 12 = 0.00345833333333333
n = number of payment months = 30 years * 12 months = 360
Substituting all the figures into equation (2), we have:
P3 = ($128,000 * (0.00345833333333333 * (1 + 0.00345833333333333)^360)) / (((1 + 0.00345833333333333)^360) - 1)
P3 = $622.21
Step 3: Calculation of the amount by which her monthly payment will be lower if she purchases the points
This can be calculated as follows:
Amount of reduction = P - P3 = $679.33 - $622.21 = $57.12
Therefore, the amount by which her monthly payment will be lower if she purchases the points is $57.12.

Light travels at a rate of approximately 186,000 miles per second. The North Star is approximately 460 light-years away from Earth. (A light-year is the distance light travels in one year.) How many yearswould it take a rockettraveling at 1 billion miles per hour to reach the North Star?
Answer:
0.0017 years
Step-by-step explanation:
Distance of North Star from Earth = 460 light years
A light year is the distance traveled by light in one year.
As per given statement:
Distance traveled by light in one second = 18600 miles
Distance traveled by light in one year ([tex]60 \times 60 \times 24\times 365[/tex]) = 18600 [tex]\times[/tex] 31536000 miles = 14506560000 = 14.51 [tex]\times[/tex] [tex]10^9[/tex] miles
We know that:
1 billion = [tex]10^9[/tex]
Therefore, 14.51 [tex]\times[/tex] [tex]10^9[/tex] miles = 14.51 billion miles
Also, it is given that speed of rocket = 1 billion miles per hour
Formula to represent relationship between Speed, Distance and Time is given as:
[tex]Distance = Speed \times Time[/tex]
[tex]Time = \dfrac{Distance}{Speed}[/tex]
[tex]Time =\dfrac{14.51\ billion\ miles}{1\ billion\ per\ hour}\\\Rightarrow Time = 14.51\ hours[/tex]
OR
0.0017 years

The population of a town is increasing at a constant rate of 4.7% each year. At the beginning of 2010 the population was 42,000. Find the size of the population at the beginning of 2016. Give your answer to 3 sf.
Answer:
The population at the beginning of 2016 is 55,326.
Step-by-step explanation:
Giving the following information:
Population 2010 (PV)= 42,000
Growth rate (g)= 4.7% = 0.047
Number of years (n)= 6 years
To calculate the population at the beginning of 2016, we need to use the following formula:
FV= PV*(1+g)^n
FV= 42,000*(1.047^6)
FV= 55,326
The population at the beginning of 2016 is 55,326.

Pluto has an average distance from the sun of 3.6 x 10^8 miles venus has an average distance from the sun of 9.0 x 10^6. How many times greater is pluto's average distance from the sun than venus?
Answer:
40 times greater
Step-by-step explanation:
Given the following:
Pluto average distance from the sun Ps = 3.6 x 10^8 miles
venus average distance from the sun Vs = 9.0 x 10^6miles
Take the ratio:
Ps/Vs = 3.6 x 10^8/9.0 x 10^6
Ps/Vs = 0.4*10^{8-6}
Ps/Vs = 0.4*10²
Ps/Vs = 40
Ps = 40Vs
Hence the pluto's average distance from the sun is 40 times greater than that of venus
