Question

According to Wikipedia, the best-selling album in 2005 was Mariah Carey’s The Emancipation of Mimi. The best-selling album in 2004 was the album Confession by Usher. Confession sold 0.94 million copies less than twice the amount The Emancipation of Mimi sold. The sum of these two albums was 13.97 million copies. Determine the sales of both albums.

Answer 1

9 million (Number of "Confession" sold)
4.97 million (Number of "Emancipation" sold)

Answer 2

problems setting the equations up? or solving the equations? or both?
or are you just looking for the answer?

Answer 3

both

Answer 4

ok, pick one album and call it X... say Confession
and label the other one Y

Answer 5

the sum of the sales was 13.97... of X and Y.... can you set up this equation?

Answer 6

no

Answer 7

what do you do to get a sum?

Answer 8

@Chrisblendz Can you at least give it a try!

Answer 9

so confused

Answer 10

when you sum a list of numbers, what do you do to get the total?

Answer 11

All you do is step by step! What is Sum?

Answer 12

13.97

Answer 13

Suppose you shop for 2 hats red and blue. How do you find out total?

Answer 14

From 2

Answer 15

what operation?

Answer 16

x y

Answer 17

Suppose red hat and blue hat are red r and blue b is

Answer 18

What you do with AND

Answer 19

x, y or r, b are operands
What kind of operation to connect them together?

Answer 20

+*/

Answer 21

minus

Answer 22

Yes, now we want total, so you should choose exactly one operation!

Answer 23

ok it should be *

Answer 24

Now your first rule to memorize TOTAL means ADDITION!

Answer 25

oh yeah that is right

Answer 26

x + y= 13.97

Answer 27

Since "The sum of these two albums was 13.97 " Can you write the expression for me. Suppose M is Emancipation and C is Confession:

Answer 28

m + c=13.97

Answer 29

It's crystal clear with SUM now :)

Answer 30

yes thank you for taking the time to help. :)

Answer 31

Since we have 2 variables m and c => We need 2 equations to solve!

Answer 32

Can you express "twice the amount of The Emancipation "

Answer 33

yes

Answer 34

Write it down for me, will you?

Answer 35

wouldn't it be that same as sum?

Answer 36

What operation is it?

Answer 37

+

Answer 38

TWICE = DOUBLE => what operation?

Answer 39

*

Answer 40

Yep, so twice Emancipation means ??

Answer 41

multiply

Answer 42

Mutiply what with what?

Answer 43

m and c

Answer 44

Twice means double. What number is it?

Answer 45

for m?

Answer 46

"twice the amount of The Emancipation "
= 2 * M

Answer 47

Is it ok?

Answer 48

yes

Answer 49

"less than twice Emancipation "
What operation for LESS?

Answer 50

@Chrisblendz do you follow me?

Answer 51

minus

Answer 52

Yep, so " 0.94 million copies less than .." is
