Answer :
The ratio between them is
[tex]6\colon5[/tex]and in total they have $715 dollars so we have to find two numbers that:
[tex](6\cdot x)+(5\cdot x)=715[/tex]and we solve for x
[tex]\begin{gathered} x(6+5)=715 \\ x=\frac{715}{11} \\ x=65 \end{gathered}[/tex]So harry have:
[tex]65\cdot6=390[/tex]
