You’re at a restaurant, it’s
the end of a meal, and now you have to figure out how to split the bill and tip
your waiter correctly. The larger the group , the larger the bill – and your
headache. But never fear, Siri’s good at math. All you need to know is one equation:
“What is [percentage] tip of [price] split by [how many] people?” Or if you
just need to know what 20 percent of $23 is, simply dictate “23 dollars plus 20
percent ” for your new total.
