Kia's electric bill be if she used 675 kWh in a month. Only enter the number. Round to the nearest
penny if necessary.
• If total monthly electricity usage is no more than 800 kWh:
C (k)
$8.63 + $0.0865 x k,
0 <k< 400
Total Monthly Electric Charges = $10.52 + $0.098982 × Number of kWh used
$43.23 + $0.10856 x (k – 400), 400 < k
• If total monthly electricity usage is more than 800 kWh:
C(675) = $
Total Monthly Electric Charges = $89.71 + $0.119943 x Number of kWh used over 800 kWh
$10.52 + $0.098982 x k,
0 < k< 800
C (k) =
$89.71 + $0.119943 x (k- 800), 800 < k
10.52 + 0.098982 x k,
Osk
C(k) =
89.71+0.119943 x (k - 800) ks 800

$10.52 + $0.098982 x k, 0< k
$89.71 + $0.119943 x k, 800 < k
C (k) =
