# How do you translate "the answer of pages in R reams of paper in each ream has 500 pages" into an algebraic expression?

Jun 26, 2015

$500 R$ (or $500 \cdot R$)
Try some examples to see the pattern. If there is 1 ream, then there are $500 \cdot 1 = 500$ pages of paper. If there are 2 reams, then there are $500 \cdot 2 = 1000$ pages of paper. If there are 3 reams, then there are $500 \cdot 3 = 1500$ pages of paper, etc...
You can also think in terms of appropriate units. The units for the 500 are "pages of paper per ream", while the units for $R$ are "reams". When you multiply these quantities, the "reams" cancels out, leaving you with an answer in "pages of paper". For example:
$500 \setminus \frac{\setminus m b \otimes \left\{p a \ge s o f p a p e r\right\}}{\setminus m b \otimes \left\{r e a m\right\}} \setminus \times 3 \setminus m b \otimes \left\{r e a m s\right\} = 1500 \setminus m b \otimes \left\{p a \ge s o f p a p e r\right\}$
