Now you will complete this same project, but now you will rebuild it using the Case$-$Switch condition framework.

$```$

switch $($subtotal$)//$ This is also correct.

$\{//$ This first statement is your hint for $4\mathrm{.}4$ and WILL work

case decimal stotal when subtotal $>=500$:

discountPct $=\mathrm{.}2$m;

break;

case based on the Second condition:

State the discount percentage.

break;

case based on the Second condition:

State the discount percentage.

break;

default:

discountPct $=\mathrm{.}0$m;

lblRedNotice.Text $="100$ or above Only";

break;

$\}$

$```$

Remember also to comment out your previous If$-$Else$-$If from the prior program similar to the below in green.

$```$

$////$ Conditions

$//$if $($subtotal $>=500)$

$//\{$

$//$ discountPct $=\mathrm{.}2$m;

$//\}$

$//$else if $($subtotal $>=250$ && subtotal $<mtext></mtext><mn>5</mn><mn>0</mn><mn>0</mn><mi>)</mi>$

$//\{$

$//$ discountPct $=\mathrm{.}15$m;

$//\}$

$//$else if $($subtotal $>=100$ && subtotal $<mtext></mtext><mn>2</mn><mn>5</mn><mn>0</mn><mi>)</mi>$

$//\{$

$//$ discountPct $=\mathrm{.}1$m;

$//\}$

$////$ Peform Calculations

$//$decimal discountAmt $=$ subtotal $*$ discountPct;

$//$decimal invoiceTotal $=$ subtotal $-$ discountAmt;

$////$ Display in the Boxes

$//$txtDiscountPct$.$Text $=$ discountPct.ToString$("$p$1")$;

$//$txtDiscountAmt$.$Text $=$ discountAmt.ToString$("$c$")$;

$//$txtTotal$.$Text $=$ invoiceTotal.ToString$("$c$")$;
