You want to "solve" this formula for s.
7s+4
If t = ----------- , then 2t = 7s + 4. Subtract 4 from both sides. Then
2
2t - 4
7s = 2t - 4, and s = -------------- (answer)
7

Solve for w

In absolution functions;

So, the given expression can be rewritten as

Removing the absolute sign, will gibe
or 
When the second inequality os rewritten, it gives
or 
Reorder both inequalities
or 
Lastly, both inequalities are combined

So Bill will receive more Extra yield for Bill=2560-2200=360 Answer=$ 360.00
