I noticed the word "train" in the problem and I knew I had to help you! :)
Suppose Alex has 3x stamps, Freddy has 5x stamps. After Freddy gives Alex 10 stamps, Alex has 3x+10 while Freddy has 5x-10
the new ratio is 7 to 9, so we have the equation: (3x+10)/(5x-10)=7/9
9(3x+10)=7(5x-10)
27x+90=35x-70
160=8x
x=20
So Alex has 3*20=60 stamps while Freddy has 5*20=100. Together they have 160
Answer:
6^2 + 5^2 = d^2

Tax = 7 1/4% = 29/4
After tax, it would be, 89.79 + 89.79*29/4*100 = 89.79 + 2589.41/400
= 89.79+6.47 = $96.26
