Spring Scale Tension Force Problem

[whoopie88]

Homework Statement

You place a 8.10-kg television on a spring scale. If the scale reads 77.95 N, what is the acceleration due to gravity at that location?

Homework Equations

f=ma
fg=mg
fnet=mAnet
Ff=μῦF

The Attempt at a Solution

Fnet = T - Fg
mAnet = T - Fg
8.1(Anet) = T - 8.1(9.81)

Now I don't know what to do from here because I have 2 variables.. Help?

The scale reading is taken with the TV at rest, so that means there is no acceleration. So how much is F_net?
The scale reading, T, is given.
You are trying to solve for 'g', which is not 9.81 in this problem.
