1. maybe you can work with this as a model

@p = ();
\$st = 0;

for (\$i=1 ; \$i <= 3 ; \$i++) {
print "Price of item #\$i: ";
\$v = <STDIN>; chomp \$v;
\$p[\$i] = \$v;
\$st += \$v;
}
\$tax = \$st * 0.06;
\$total = \$st + \$tax;
print "\nItem Price\n";
for (\$i=1 ; \$i <= 3 ; \$i++) {
printf "%4d %12.2f\n",\$i,\$p[\$i];
}
printf "%s\n","-"x17;
printf "subtotal: %7.2f\ntax: %12.2f\ntotal: %10.2f\n",\$st,\$tax,\$total

sample run:

perl jiskha1.pl
Price of item #1: 1763.2
Price of item #2: .85
Price of item #3: 12

Item Price
1 1763.20
2 0.85
3 12.00
-----------------
subtotal: 1776.05
tax: 106.56
total: 1882.61
