The cost of 12 units would be $614.40.
This is found by dividing $204.80 by 4 to get $51.20 (cost per single unit), then multiplying $51.20 by 12 to get $614.40 (cost for 12 units).
I hope this helps!
Answer:
C. 
Step-by-step explanation:
The function t, where
represents the amount of money Fernando earns given the number of hours, x, he works.
The domain of the function
are all possible values for x.
It is known that Fernando works between 12 and 25 hours each week, so the number of hours, x, he works satisfies the inequality

Answer:
- 5-hour: 0.5277
- 1-hour: 0.8800
Step-by-step explanation:
The decay factor for time t can be written as ...
0.2785^(t/10)
Then the 5-hour decay factor is ...
0.2785^(5/10) ≈ 0.5277
and the 1-hour decay factor is ...
0.2785^(1/10) ≈ 0.8800
