Answer:Amount charged for downloading individual songs = x dollars

Amount charged for downloading an entire album = y dollars

In respect to person A:

6x + 2y = 25.92

3x + y = 12.96

y = 12.96 – 3x

In respect to person B:

4x + 3y = 33.93

Putting the value of y from the first equation in the second, we get

4x + 3(12.96 – 3x) = 33.93

4x + 38.88 – 9x = 33.93

– 5x = – 4.95

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

Which set is closed under the operation multiplication?
oee [108]
I have another set of choices here:

A. {0.5, 1, 2} 


B. {1, 2, 4} 


C. {1, 2, 3, 4, 5} 


<span>D. {0} 
</span>
If you multiply two numbers from a closed set the answer is in the set. 
<span>So A is not closed because 2 x 2 = 4 which isn't in the set. Only 0.5, 1, and 2 are in set A. </span>

<span>Try multiplying the largest numbers in sets B, C, and D by themselves. You will soon discover the closed set.</span>
