Question

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. Interpret the P-intercept of the equation.

Provide your answer below:
The P-intercept, 2.54, means that Randy's monthly water bill payment would be 2 point 5 42.54 dollars if he used 2828 units of water.

Answer 1

Step-by-step explanation: The P-intercept of the equation P = 28 + 2.54w is 28. This means that when the number of units of water used is 0 (w = 0), the amount of Randy's monthly water bill payment is 28 dollars. This is the minimum payment that Randy must make for the water usage, regardless of the actual usage.
