The bill for a person who uses 560 kWh in a month is (d) $74
<h3>How to determine the bill?</h3>
The function is given as:
- b(x) = 0.15x; x ≤ 360
- b(x) = 0.10(x - 360) + 54; x > 360
For a person who uses 560 kWh, it means that:
x > 360
So, we use the following function to determine the bill
b(x) = 0.10(x - 360) + 54
Substitute 560 for x
b(560) = 0.10(560 - 360) + 54
Evaluate
b(560) = 74
Hence, the bill for a person who uses 560 kWh in a month is (d) $74
