Answer:
Step-by-step explanation:
Given
Let R represents rows and C represents Columns
When R = 8, C = 25
When R = 10, C = 20
Required
Given that there exist an inverse variation, determine the constant of proportionality;
We start by representing the variation;
Convert proportion to an equation
Where k is the constant of proportion;
Multiply both sides by C
Reorder
<em>When R = 8, C = 25;</em>
<em>The equation </em> <em>becomes</em>
<em>When R = 10, C = 20;</em>
<em>The equation </em> <em>becomes</em>
Hence, the concept of proportionality is 200
