Answer:
Plan B
Step-by-step explanation:
Let's calculate the amount required for each plan
<h3>Plan A</h3>
- 0.15*200 + 0.10*100 = $40
<h3>Plan B</h3>
- 15 + 200*0.05 + 100*0.05 = $30
As we see Plan B costs less
He gets 7.80 an hour so you multiply 7.8 by 5.25 hours

Answer:
after 10 seconds the charge is 1.624
Step-by-step explanation:
I think your question missed key information, allow me to add in and hope it will fit the orginal one.
The electrical charge on a metal plate is given by the function below, where t is the time in seconds. What is the charge after 10 seconds?
C (t) = 12
My answer:
Given the information:
C (t) = 12
when t =10 we have:
C (10) = 12
<=> C (10) = 12
<=> C (10) = 12
<=> C (10) = 12 * 0.1353
<=> C (10) = 1.624
Hence, after 10 seconds the charge is 1.624
