Question

An electric company charges each of its customers a monthly fee of $19 to maintain the account and $0.09 per kilowatt-hour. What is an equation that relates the monthly cost, C, in dollars and the amount of power consumed, P, in kilowatt-hours?(1 point)

C=0.09P+19

C=0.19P+9

C=0.19P+0.09

C=0.28P

There's a flat $19 fee:

C = 19 + ...

And then there is an amount based on the power consumed (0.09 for each P consumed).

C = 19 + 0.09P

The commutative property says we can add in either order, so swap it around:

C = 0.09P + 19

Which one does that match with?

Answer:

A) C = 0.09P + 19

Answer 2

monthly cost C = 0.09 P + 19 ...............ANS

Answer 3

First one is correct.

$19 + $0.08 x P
