Remark

Drawing that diagram was a very good idea. If you can picture something happening, you are half way there. I tend to use a table, but the diagram will come to the same thing.

                  Olivia                    Dawn

Start            176                         80

<u>Donate         x                             x      Subtract</u>

What's left   176 - x                  80 - x

Equation

176 - x = 5*(80 - x)     Olivia had 5 times as many books as Dawn did.   Remove the brackets.      

Solution

176 - x = 400 - 5x                 Add 5x to both sides

176 + 5x - x = 400                  Combine terms on the left

176 + 4x = 400                    Subtract 176 from both sides

4x = 400 - 176                     Combine terms on the right.

4x = 224                              Divide by 4

x = 224/4    

x = 56                                 Answer

Make a comparison between the government’s roles in a capitalist economic system versus a socialist or communist economic system
Masteriza [31]
Hello!

In a Capitalist Economic System, the government is expected to guarantee the respect to private property, promulgate laws that defend economic freedom, and is an intermediary between the private sector and society. In this economic system, the government is reduced an doesn't intervene in the free market. 

In a Socialist or Communist Economic System, the government redistributes goods and services, takes the means of production (private property) from their owners to put them in service of the working class, promulgate laws that limit economic freedom and heavily intervenes in the market and economy.

Have a nice day!
