Is Wednesday meant to be an apple and a pear?

Either that, or there's some serious inflation going on at this greengrocers!

You could use algebra, but the easiest way is to just add up what she bought over the 3 days.

i.e. 2 apples, 2 bananas and 2 pears cost £1.82

You should then be able to work out what 1 apple, 1 banana and 1 pear cost.

There is no need for algebra for this question! :)

Just note that every fruit appears twice and add up all the costs, as said above.

This is the sort of question I throw in to show students that using algebra is sometimes a long-winded approach.

I just deduced that pear 1p less than apple
Pear 12p more than banana.
If A +P = 69p then A=35p and P=34p
If B+P =56p then B=22p and P=34p
Can then add together A,B and P.

BUT the above answer is easier than my way!
