Answer:
yes it's a solution. I think. I don't really know this
1/4 of 1 minute would be 1/4 * 60(seconds in a minute)
so that would be 60/4=15 seconds.
82 = (n + 10) + n + [2(n + 10)]
Solve that ad you will have your numbers. Don't forget to simplify the terms first before you start solving.
Answer: 1210.1
Step-by-step explanation:
For each person the Total paid = cost of 7 fire alarms + the installation fee.
To find the installation fees consider the following: F = installation fee
Peter: 452.98 = 7(59.59) + F therefore F = 35.85
Ashley: 453.39 = 7(58,29) + F therefore F = 45.36
Now we find the difference between the two fees: 45.36 - 35.85 = 9.51
