Monday to Friday is the challenge. So you have a total of $11.25 to spend.
$7.43 gives you 1.5 tins of bake beans per day.
(half a tin for breakfast on one piece of toast, half a tin for lunch on one piece of toast, half a tin for dinner on one piece of toast).
Need total of 15 slices of bread, should be more than that in two loafs (two loafs = $2.94)
Total = $ 10.37 ($0.88 left)
