Marianna [84]

Assuming this economy is closed: Consumption $6.9 trillion; Government Purchases $11.2 trillion; National Saving $2.3 trillion; Investment $2.3 trillion.

<h3>Gross domestic product</h3>

a. Consumption

Private S = ( Y – T – C )

C = Y - T - Private S

C = $12 - $3.6 - $1.5 =$6.9 trillion

b. Government purchases

Public S = ( T - G )

G = T - Public S

G = $12 - $0.8

G = $11.2 trillion

c and d. National saving and investment

National savings = Public S + Private S

National savings = $0.8 + $1.5

National savings =$2.3 trillion

Investment=Savings=$2.3 trillion

Therefore, Consumption $6.9 trillion; Government Purchases $11.2 trillion; National Saving $2.3 trillion; Investment $2.3 trillion.

An algebraic expression is an expression in which it involves the numbers like 1,2,3 also it includes the operations such as additions, subtraction, multiplication, etc

Fo mentioning an algebraic expression, we do have following components

x = number of consoles purchased

y = number of games purchased

z = number of controllers purchased

C = total cost

Also, the total cost would be equivalent to the sum of the price and then it multiplied with the numbers as stated above

Solve this problem: 3(6 - 8)² + 8÷2<br> A-8<br> B-16<br> C-28<br> Will mark Brainliest!!

marishachu [46]

Answer: 16

Step-by-step explanation: When you have a set of parentheses in an order of operations problem, you must simplify what's inside that set of parentheses first before you do anything else.

So our first step here is to subtract 6 - 8 which gives us -2.

So in our next step we have 3 (-2)² + 8 ÷ 2.

Now remember to do exponents before you multiply.

So (-2)² is just -2 × -2 or 4.

So in our next step we have 3 x 4 + 8 ÷ 2.

Now, we multiply so we have 3 x 4 which is 12.

So we have 12 + 8 ÷ 2.

Now we can divide.

8 ÷ 2 is 4 so we have 12 + 4 or 16.

So the answer to this problem is 16.
