A table of values can be used to represent variables that are directly proportional.
The complete table of proportions is:
Given that
Let:
<em /><em> Letters</em>
<em /><em> Cost</em>
<em />
Using proportional reasoning, we have:
Where
<em /><em> ratio of proportion</em>
For the first values of C and L, we have:
Divide both sides by 10
So, the equation of proportion is:
<u>When C = 6.75, we have:</u>
Solve for L
<u>When L = 7, we have:</u>
<u>When L = 1, we have:</u>
<u>When L = 500, we have:</u>
<u>When C = 18.90, we have:</u>
Solve for L
Hence, the complete table is:
