Juliet is selling photographs as part of a project for her entrepreneurship class. She sells the first 20 photographs for $10 ea

Murljashka [212]

Answer:

option (B) 20

Step-by-step explanation:

Data provided in the question:

Number of photographs initially sold = 20

selling price of first 20 photographs = $10 each

Therefore,

Revenue from 20 photographs = 20 × $10 = $200

Selling price of further photographs = $15

Let the number of additional photographs sold be 'x'

thus,

total revenue = $200 + $15x

now,

according to the question

80% of ($200 + $15x) = $400

0.80 × ($200 + $15x) = $400

($200 + $15x) = $500

$15x = $300

x = 20

Hence,

the answer is option (B) 20

The second term in a geometric sequence is 20. The fourth term in the same sequence is 11.25. What is the common ratio

damaskus [11]

Let $a_n$ be the n'th term of the sequence.

so $a_1$ is the first term, $a_2$ the second term and so on...

In a geometric sequence with $a_1=c$ , and common ratio r, the terms are as follows:

$a_1=c$
$a_2=cr$
$a_3=c r^{2}$
$a_4=c r^{3}$
.
.
that is, each term is its previous term times the common ratio r.

In our example

$a_2=cr=20$ and $a_4=c r^{3}=11.25$

$\frac{a_2}{a_4}= \frac{cr}{c r^{3}}= \frac{1}{ r^{2}}= \frac{20}{11.25}= 1.778$

so $r^{2} =1/1.778=0.56$

$r= \sqrt{0.56}= 0.75$

Answer: r=0.75
