The electric bill charge for a certain utility company is
$0.016
per kilowatt-hour plus a fixed monthly tax of
$11.37
. The total cost,
y
, depends on the number of kilowatt-hours,
x
, according to the equation
=y≥+0.016x11.37, x0
.
(b) Determine the cost of using kilowatt-hours.
The cost of using
2000
kilowatt-hours is
$
.
To determine the cost of using 2000 kilowatt-hours, we can substitute 2000 for x in the equation:
y = 0.016x + 11.37
y = 0.016(2000) + 11.37
y = 32 + 11.37
y = $43.37
So the cost of using 2000 kilowatt-hours is $43.37.
To determine the cost of using 2000 kilowatt-hours, you can substitute 2000 for x in the equation and calculate the value of y.
Given:
Cost equation: y = 0.016x + 11.37
Substituting the value of x:
y = 0.016(2000) + 11.37
Calculating:
y = 32 + 11.37
y = 43.37
Therefore, the cost of using 2000 kilowatt-hours is $43.37.
To determine the cost of using 2000 kilowatt-hours, we can substitute the value of x into the equation and calculate the value of y.
Given:
Cost per kilowatt-hour (m) = $0.016
Fixed monthly tax (b) = $11.37
Number of kilowatt-hours (x) = 2000
Cost (y) = ?
The equation is: y = mx + b
Substituting the given values:
y = 0.016(2000) + 11.37
Calculating the expression:
y = 32 + 11.37
Simplifying:
y = 43.37
Therefore, the cost of using 2000 kilowatt-hours is $43.37.
