Phase Diagram Practice Problems: Pt$.1$

Part I: Use the Cu$-$Ag Phase Diagram for the following question

$1$: Your alloy contains $\backslash (60\backslash \%\backslash$mathrm$\{$Ag$\}\backslash )$ and is at temperature $\backslash (800^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash )$

a$)$ What phases are present in the alloy at this point?

b$)$ What are the compositions of the phases present at this point?

c$)$ What proportions of the two phases make up the alloy at this point? $($Draw a tie line and perform lever rule calculations below$)$
