(a) Determine the cost of using kilowatt-hours.
The cost of using
1000
kilowatt-hours is
$
.
The cost of using 1000 kilowatt-hours can be found by substituting x = 1000 into the equation y = 0.016x + 11.37:
y = 0.016 * 1000 + 11.37
= 16 + 11.37
= 27.37
Therefore, the cost of using 1000 kilowatt-hours is $27.37.
To determine the cost of using 1000 kilowatt-hours, we can use the given equation:
y = 0.016x + 11.37
Substitute x = 1000 into the equation:
y = 0.016(1000) + 11.37
y = 16 + 11.37
y = 27.37
Therefore, the cost of using 1000 kilowatt-hours is $27.37.
To determine the cost of using 1000 kilowatt-hours, we can substitute x = 1000 into the equation and calculate y.
Cost, y = 0.016x + 11.37
= 0.016(1000) + 11.37
= 16 + 11.37
= $27.37
Therefore, the cost of using 1000 kilowatt-hours is $27.37.
