Sedbober [7]
A = $ 861.69

Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year,
putting time into years for simplicity,
1 quarters ÷ 4 quarters/year = 0.25 years,
then, solving our equation

A = 850(1 + (0.055 × 0.25)) = 861.6875 
A = $ 861.69

The total amount accrued, principal plus interest,
from simple interest on a principal of $ 850.00
at a rate of 5.5% per year
for 0.25 years (1 quarters) is $ 861.69.

babymother [125]

Answer:

The answer is "option b"

Step-by-step explanation:

Amount = $26,900

r= 0.0818 %

i=\frac{r}{4}\\\\

 =\frac{0.0818}{4}\\\\=0.02045

t= 8 years

n= 8 \times 4

  =32

D=\frac{1-(1+i)^{-n}}{i}\\

   =\frac{1-(1+0.02045)^{-32}}{0.02045}\\\\=\frac{1-(1.02045)^{-32}}{0.02045}\\\\=\frac{1-0.52319627}{0.02045}\\\\=\frac{0.47680373}{0.02045}\\\\=23.3155858

Q= \frac{Amount}{Discount \ factor }\\

   =\frac{26900}{23.3155858} \\\\=1153.73468

Payment =1153.73468 \times  32\\\\

               = \$ 36919.5098\\

\text{Total interest = Payment - amount}

                    = \$ 36919.5098 - \$ 26900 \\\\                      = \$ 10019.5098

\text{Finance charge = Total interest + service charge}

                        = \$ 10019.5098 + \$ 1527\\\\                          = \$ 11546.5098

A photographer uses an online service to sell some of his work. The amount of money he will make from selling 10 copies of the s
VLD [36.1K]

Answer:

Step-by-step explanation:

The expression representing the amount of money that the photographer would make from selling 10 copies is given as

10(0.75p - 0.5)

where p represents the price determined for each copy. Assuming the price charged per copy is $5, then the amount made from 10 copies is

10(0.75 × 5 - 0.5) = $32.5

It could have been

10(5 - 0.5) = $45

The price is being reduced by 25%(100 - 75)

Therefore, the option that most likely describes the agreement between the online service company and the photographer is

A. The company keeps 25% of the amount paid for each copy and charges the photographer $0.50 for every copy purchased.
