A shop sells tea bags in boxes of 80 and in boxes of 120.

A box of 80 tea bags costs $2.36.
a Work out the cost of 40 of these tea bags.
A box of 120 tea bags $3.45.
b Work out the cost of 40 of these tea bags.
c Which box of tea bags is better value for money?

1 answer

a) 40 tea bags would be half of an 80-tea bag box, so it would cost half the price of a box, which would be:

2.36 ÷ 2 = $1.18

Therefore, 40 tea bags cost $1.18.

b) 40 tea bags would be one-third of a 120-tea bag box, so it would cost one-third of the price of a box, which would be:

3.45 ÷ 3 = $1.15

Therefore, 40 tea bags cost $1.15.

c) Since 40 tea bags cost less in the box of 120 than in the box of 80, the box of 120 is better value for money.
