Customers who use electricity in off peak hours in orangeburg pay a $12 meter per month plus $0.0365 per kilowatt-hour. Which equation represents the total cost 'c' of a monthly electric bill as a function of kilowatt-hours 'k' ? A. c = 0.0365k + 12
B. c = 0.0365(k + 12)
C. c + 12 = 0.0365
D. k = 0.0365(c + 12)
E. k = 0.0365c + 12

A. c = 0.0365k + 12

Step-by-step explanation:

First, answer choices D and E are wrong because they represent k as a function of c.

Answer choices B and C are wrong because they incorrectly represent the cost including the monthly cost and kilowatt-hour price.

Answer choice A is correct because it properly represents the cost per kilowatt-hour (0.0365k) and properly adds the monthly cost ($12)

So, A is the right answer.
