To determine

## To find:The equation given that the statement

Expert Solution

The equation is P=kw

### Explanation of Solution

Given:

P varies directly as w

Concept used:

If the quantities x and y are related by an equation

y=kx

For some constant k0

That is y varies directly as x or y is directly proportional to x

The constant k is called constant proportionality

Calculation:
