SANDWICHES

we will be ordering from our school canteen,
as it's will be cheaper also & it's more convenient for us.

Normally they will sell at 1 for $1-$1.10
We can cut the sandwiches into half again.

Since there will be 220 people there,
we will need to order 110 sandwiches from them.

$1.10 x 110 = $121
