Answer:
50 cent
Step-by-step explanation:
Given that :
Cost of energy = $0.068 per kilowatt-hour (kWh)
Number of bulbs = two 10 watt bulbs
Converting the power of the bulb to kilowatt :
2 * 10watt = 20 watt
1000 watt = 1 kilowatt
20 watt = x
1000x = 20
x = 20/1000
x = 0.02 kW
Cost of Energy consumed by bulb 1 hour for 365 days :
0.02kW * 1 * 365 * $0.068 = $0.4964
$0.4964 to cent
100 cent = $1
$0.4964 * 100 = 49.64 cent
49.64 = 50 (nearest cent)
Average cost per mile is $0.6
<h3>How to calculate the average cost per mile?</h3>
To calculate the average cost per mile that Kiara had to pay, we perform the following operations:
We add up all the payments Kiara made related to her car.
- $3,060 + $94 + $128 + $1,080 + $290 + $398 + $1,520 + $930 = $7,500
Later we divide the total value, in the number of miles traveled by Kiara
- $7,500 ÷ 12,500 miles = 0.6

Answer:
F(4) = 23
Step-by-step explanation:
Find F(4) also means finf F = 4x + 7 when x =4
When x = 4, it would be:
F = 4*4 +7
F = 16 + 7
F = 23
F(4) = 23
