b)
For each food group, find the total amount of servings and percentage of the
total servings that Mr. Smith buys.
c)
Compare the percentages obtained in parts a
and b by making two pie charts. What would your suggestions be for a better
balanced grocery list?
d)
According to question 1, how many days of balanced nutrition can the shopping
list provide for 1 person?
e)
Mr. Smith knows that 2/3 of the time his family eats out or orders food
in. How many more servings and from
which food groups does he need, to make the home meals balanced for his entire
family for a week?
After
thinking about his grocery list, Mr. Smith decides to buy more food that will
help him to create healthier meal choices.
3)
a)
Mr. Smith wants to replace candy with strawberries on his weekly grocery
list. If he decides to buy 2 kg of
strawberries a week, make a bar graph depicting the amount that he will pay
over a year for the possible choices.
There
are three choices:
Choice
1: $4.28/kg
Choice
2: $2.18/200g box
Choice
3: $5.98 /4lb box
b)
Which choice is the best, and how much money will he save over a year with that
choice?
c)
Mr. Smith decided that he is going to buy twice as much pasta (by weight) than
the mass of oranges he was buying. If he
buys $3 dollars worth of oranges, and oranges cost $0.99 a pound, how much
pasta is he buying?
Mr.
Smith is done shopping and is now standing in line.
4)
a)
He estimates that he will need to buy 11 plastic bags to put his groceries
in. Each plastic bag costs 4 cents. If
he goes shopping every week, how much money would he save over a year if he reused
his bags instead of buying new ones every time?
b)
Mr. Smith pays $17.57 tax for his groceries. If the tax for his goods is 7%,
what is the total amount he paid?
After
Mr. Smith got the receipt, he placed all the groceries in a storage locker and
went to join up with the rest of his family.
