1. Fiscal differences

Democrats are usually pro-regulation, and Republicans are for a free market. However, both are pro-capitalism. Examples: 15 dollar minimum wage, Green New Deal

2. Social differences

Democrats tend to be more progressive in social view, meanwhile Republicans tend to want to stick to the traditions. This means LGBT, abortion BLM, etc.  

3. Climate change

Most Democrats recognize that climate change is a problem (they wont do anything about it, but at least they recognize it I guess.) Most Republicans think that climate change is normal and there is nothing to do about it.

makkiz [27]

The expression for the cost of Taxi B is 0.40<em>x</em> + 2.<em>  </em>The expression for the cost of Taxi A is 0.20<em>x</em> + 4.  The inequality asks for when the cost of Taxi B will be greater than Taxi A, so you write it as 0.40<em>x </em>+ 2 > 0.20<em>x</em> + 4,  or  0.20<em>x</em> + 4 < 0.40<em>x </em>+ 2.

The answer is B) 0.20<em>x</em> + 4 < 0.40<em>x </em>+ 2.

If the simple interest on ​$4000 for 8 years is ​$2240​, then what is the interest​ rate?
mixer [17]

~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\dotfill & \$2240\\ P=\textit{original amount deposited}\dotfill & \$4000\\ r=rate\to r\%\to \frac{r}{100}\\ t=years\dotfill &8 \end{cases} \\\\\\ 2240 = (4000)(\frac{r}{100})(8) \implies 2240=\cfrac{32000r}{100}\implies 2240=320r \\\\\\ \cfrac{2240}{320}=r\implies 7=r
