Real-Life Math -- Solution
At the grocery store, your food purchases add up as follows:
$2.88
milk + $ 1.80 eggs + $2.55 crackers = $7.23 total
Next,
you need to add up diapers and formula, then add the total to the cost of
the groceries:
$14 diapers + $12 baby formula = $26 total
$7.23
+ $26 = $33.23
The total for all your purchases is $33.23.
How much spending money do you have left over?
$50 - $33.23
= $16.77
This leaves you $16.77 in spending money. But
what about dairy treats?
$2.75 x 3 = $8.25
Dairy
treats for all three children cost $8.25.
$16.77
- $8.25 = $8.52
After all your purchases, plus treating
the kids, you'll still have $8.52 left over.
Being able to budget money
is just one way nannies use math. You'll also need to help children with their
math homework, too -- so be sure to brush up on your own math skills if you
plan to become a nanny!
Nanny Crystal Perry agrees. "Children always
need help with homework, and I have found that I had forgotten a lot of things
after high school!"
"Math is used a lot when you look after school-age
children who have math homework," says Cheryl-Leah Coultis, who has worked
as a nanny in Canada, the U.S., England and Germany. "Also, you will use math
when you are looking after preschool children who are learning about numbers
and what plus and minus mean."
