Task 1
He has decided that each person has
to have one of two presents that they
will LOVE to open on Christmas Day.
You must decide which of the two
presents to buy for each person,
but you have a budget of only £140
to use in total.

in his piggy bank to
spend, which
includes wrapping
paper!

Task 2
The presents need to be wrapped up!
You need to calculate the number of
rolls of wrapping paper that will be
needed.
There is a choice of paper, each roll has a
different price.
You do NOT have to use the same paper for
each present.

The six presents all need
wrapping paper!
There are 4 designs to
choose from, and each costs
a little bit more or less.
Remember you have a total of
£140 for presents and paper,
so choose the paper wisely!
