andrew-mc [135]
Let the amount of money be M, 

then Mr.Scruggs spent 1/5M <span>on dog treats, and so 4/5M was left.

4/5M was equally divided in 3 parts among his favourite charities, so each of these received:
</span>\frac{ \frac{4}{5}M }{3}=\frac{4}{5}M* \frac{1}{3}=\frac{4}{15}M
<span>
i) each charity received 4/15 of the money.

ii) 
</span>\frac{4}{15}M=$60
<span>
4M=15*60
M=15*15

M= 225 (dollars).


Check: 4/5(225)=4*45=180,    180/3=60</span>
