The entire code example now reads:
$cash_on_hand = 31;
$meal = 25;
$tax = 10;
$tip = 10;
while(($cost = restaurant_check($meal,$tax,$tip)) < $cash_on_hand) {

$tax_amount = $meal * ($tax / 100);
$tip_amount = $meal * ($tip / 100);
return $meal + $tax_amount + $tip_amount;
}
And the corresponding answer block in appendix C, section C.5.3 (page 303)
now reads:
I can afford a tip of 10% (30)
I can afford a tip of 11% (30.25)
I can afford a tip of 12% (30.5)
