how is per capita gross domestic product calculated "total market value of goods and services produced within a year divided by
kakasveta [241]

Answer: See explanation

Step-by-step explanation:

You didn't really say what you want to know but let me explain.

The gross domestic product of an economy is the value of the goods and.d services that are being produced in such an economy. The gross domestic Product is used to know how well an economy is doing

Per capita gross domestic product (GDP) is a used to know the economic output of a particular country per person. It is calculated by dividing the GDP of such an economy by the population.

For example, let us say the GDP of a country is $800,000,000 and the population is 3,500,254. Therefore, the per capita GDP would be:

= $800,000,000 / 3,500,254

= $228.56 per person

Six times the number of cattle less 87 is 999
AveGali [126]
You have to translate the statement into a mathematical expression...

Six times the number of cattle, if we let c be the number of cattle is:

6c

Less 87 means to subtract 87 so

6c-87

is 999 means

=999

so all together we have:

6c-87=999  now we need to isolate the variable by itself on one side of the equal sign....

6c-87=999  add 87 to both sides

6c=1086  divide both sides by 6

c=181

So there are 181 cattle.

Gage's math teacher entered the seventh-grade student in a math competition. There was an enrollment fee of $30 and also $11 cha
Amanda [17]

Answer:

110 test

Step-by-step explanation:

Let

x ----> the number  of packet of 10 test

y ----> the total cost

we know that

The number of packet of 10 test purchase multiplied by $11 plus the enrollment fee of $30 must be equal to $151

so

The linear equation that represent this scenario is

y=11x+30

we have

y=\$151

substitute

151=11x+30

Solve for x

subtract 30 both sides

11x=151-30

11x=121

Divide by 11 both sides

x=11

The number of packets purchase was 11

To find out the number of test, multiply the number of packets by 10

11(10)=110\ test
