184/525
(this is me adding characters)
If she only had 1 hour sessions she had 8 sessions in the first week because if you do 35 times 8 you get 280.
Sixteen because if there are eight less tigers than lions at a zoo, then that means you add 8 to get the number of lions
8/3=3x (cross multiplied to get this)
X=8/9 (divided both sides by 3)
Hope this helps :)
