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

Which choice is the explicit formula for the following geometric sequence?0.5, -0.1, 0.02, -0.004, 0.0008, ...

Minchanka [31]

$a_1=0.5\\a_2=-0.1\\a_3=0.02\\a_4=-0.004\\a_5=0.0008\\\\a_n=a_1\cdot q^{n-1}\\\\q=a_2:a_1\to q=-0.1:0.5=-0.2\\\\a_n=0.5\cdot(-0.2)^{n-1}=0.5\cdot(-0,2)^n\cdot(-0.2)^{-1}\\\\=0.5\cdot(-0.2)^n\cdot(-5)=-2.5\cdot(-0.2)^n\\\\\boxed{a_n=-2.5\cdot(-0.2)^n}$
