Mathematics: The electricity rates charged by monroe utilities in the summer months are as follows: base charge = $ 8 $8 first 800 800 kwh or less at $ 0.05 $0.05/kwh over 800 800 kwh at $ 0.08 $0.08/kwh the base is a fixed monthly charge, independent of the kwh (kilowatt-hours) used during the month. a . a. find an expression for the cost function c ( x ) c(x) for usage of or under 800 800 kwh.

$C(x) = \$8 + \$0.05*x$

Step-by-step explanation:

Let 'x' be the usage in kWh. When usage is at or under 800 kWh, the cost function C(x) is given by the base charge of $8 added to the rate of $0.05/kWh multiplied by the consumption 'x', in kWh.

Therefore, for 0 ≤ x ≤ 800, the cost function is:

$C(x) = \$8 + \$0.05*x$
