Real-Life Math -- Solution
You rush back to the counter to get the calculator, only to find
it's missing. You'll have to do this on your scratch pad.
First, you'll
need to add up what each customer had. Then add the tax. Remember, tax applies
to the whole meal. The liquor tax applies only to the wine and cocktails.
Customer
on left
$17.50 (fish)
$4.00 (wine)
$4.50 (cocktail)
$26.00
subtotal x 7 percent tax = $1.82
$8.50 liquor total x 10 percent
liquor tax = $0.85
$26.00 + $1.82 + $0.85 = $28.67
Customer
on right
$14.95 (chicken)
$4.00 (wine)
$4.50 (cocktail)
$23.45
subtotal x 7 percent tax = $1.64
$8.50 liquor total x 10 percent
liquor tax = $0.85
$23.45 + $1.64 +$0 .85 = $25.94
The customer
on the left owes $28.67 for his portion of the bill, and the customer on the
right owes $25.94 for her portion of the bill.
You will need to have
a handle on math to make it in this career. This is especially true for the
better-paying jobs. Helene Fernendes is in charge of hiring for a company
provides food services to schools and hospitals.
She's unlikely to
hire someone as a dietary aid or even as a server unless they have taken some
community college training.
