Question

The equation P= 28 +2.54w models the relation between the amount of Randy's monthly water bill payment, P, indollars, and the number of units of water, w, used. Interpret the P-intercept of the equation.

Answer 1

Given:

The equation

$P=28+2.54w$

models the relation between the amount of Randy's monthly water bill payment, P, in dollars, and the number of units of water, w, used.

Required:

To find the P-intercept of the equation.

Explanation:

Consider the given equation,

$P=28+2.54w$

The P -intercept means that if the number units of water Randy used was 0 , the payment would be

$\begin{gathered} P=28+2.54(0) \\ P=28 \end{gathered}$

Final Answer:

P-intercept is 28.

That means payment would be $28.
