Amount charged for downloading individual songs = x dollars
Amount charged for downloading an entire song album = y dollars
Person A:
6x + 2y = 25.92
3x + y = 12.96
y = 12.96 - 3x
Person B:
4x + 3y = 33.93
Putting the value of y from the first equation in the second we get
x = 0.99 dollars
Putting the value of x in the first equation we get
y = 12.96 - 3x
= 12.96 - 2.97
= 9.99 dollars
Complete question :
A bookstore manager marks down the price of older hardcover books, which originally sell for b dollars, by 52%.
a. Write the markdown as a decimal. b. Write an expression for the sale price of the hardcover book.
Answer:
0.52 ; 0.52b
Step-by-step explanation:
The markdown percentage = 52%
Expresaing markdown as a decimal :
52% = 52 / 100 = 0.52
Expression for the sale price of hardcover book:

Hence, sales price becomes ;
Original price * markdown
b * 0.52
0.52b

Determine the equilibrium price
This is determined when Demand = Supply
So:
Collect Like Terms
Solve for x
<em>Hence; The equilibrium price is when x = 52.00</em>
Answer:
(2.3 times 10^4) is less than (1.15 times 10^8). That means that every single one of these answer options is wrong. However, If the problem were how many times bigger is 1.15 x 10^8 than 2.3 x 10^4 then the answer would be 5000. So therefore all of these answers are incorrect. I now understand why you are so desperate for this answer!
