Answer:

$40

Step-by-step explanation:

Let the total bill be "x"

Now,

Anna paid 40% (40/100 = 0.4) of the bill, that means

Cassie paid 100 - 40 = 60% of the bill, that is 60/100 = 0.6

Anna paid 0.4x & Cassie paid 0.6x

Cassie's amount is 8 dollar more, so we can write:

0.6x - 8 = 0.4x

Now, we solve for x:

0.6x - 0.4x = 8

0.2x = 8

x = 8/0.2

x = 40

THe total bill is $40

Fed [463]

Using a system of equations, it is found that:

There are 8 chickens in the yard.

There are 16 pigs in the yard.

-----------------------------------------

This question is solved using a system of equations. I am going to say that:

x is the number of chickens.

y is the number of pigs.

-----------------------------------------

A chicken has 1 head, as do a pig.
There are 24 heads.

Thus:

$x + y = 24 \rightarrow y = 24 - x$

-----------------------------------------

A chicken has 2 feet.
A pig has 4 feet.
In total, there are 80 feet.

Thus:

$2x + 4y = 80$

-----------------------------------------

Number of chicken:

Since $y = 24 - x$

$2x + 4y = 80$

$2x + 4(24 - x) = 80$

$2x + 96 - 4x = 80$

$2x = 16$

$x = \frac{16}{2}$

$x = 8$

There are 8 chickens in the yard.

-----------------------------------------

Number of pigs:

$y = 24 - x = 24 - 8 = 16$

There are 16 pigs in the yard.

alukav5142 [94]

Answer:

62. 84%

Step-by-step explanation:

total revenue of a company from music sales and licensing in 1999 = $14.8 billion

Foretasted total revenue of a company from music sales and licensing in 2014 = $5.5 billion

decrease in revenue of a company from music sales and licensing in 2014 from 1999 = $14.8 billion - $5.5 billion = 9.3 billion

Therefore percentage decrease in music revenue =( difference in revenue from 1999 to 2014/ revenue in 1999 ) * 100

$(9.3 \ billion/14.8 \ billion) * 100\\=> 0.6284 *100 \\=> 62.84 %\\$

percent decrease in music revenue is 62. 84%.
