First make a guest check
My Guest check #9
1 donut = $1.29
Donut holes = $4.89
Dozen Donuts = $12
Donut Holes = $4.89
$1.29 + $4.89 + $12 + $4.89 = $23.07
$23.07 * 8% =<em> $24.92 is the 9th check list</em>
My Guest check #10
1 donut = $1.29
1 donut = $1.29
Dozen Donuts = $12
Donut Holes = $4.89
$1.29 + $1.29 + $12 + $4.89 = $19.47
$19.47 * 8% = <em>$21.03 is the 10th check list</em>
