Let Mr. Scuggs got x money on his birthaday.
The spent mone on dog treats is 1/5 means that 1/5x.
1:
Determine the money he left after dog treats.
[tex]\begin{gathered} x-\frac{1}{5}x=\frac{5x-x}{5} \\ =\frac{4x}{5} \end{gathered}[/tex]
The remaining money is divided among 3 charities.
Determine the money recieved by each charity.
[tex]\begin{gathered} \frac{\frac{4x}{5}}{3}=\frac{4x}{5\cdot3} \\ =\frac{4x}{15} \end{gathered}[/tex]
The fraction of money exh charity recieve is 4/15.
2:
The equation for the x is 4x/15 = 60.
Smplify the equation for x.
[tex]\begin{gathered} \frac{4x}{15}=60 \\ x=\frac{60\cdot15}{4} \\ =15\cdot15 \\ =225 \end{gathered}[/tex]
So, he recieve 225 on his birthday.
