Math mate post on blog term 4 week 8 question 22


Predict: I predict this question will be about cost.

Read: Which deal costs less per millimeter?

Clarify: I had nothing to clarify

Mathematicians toolbox: i used have i seen a similar problem before.

Big question: The big question is which deal costs less per milliliter

Solve: First looked at the possible answers  and b had more cost so i doubled a and i found that the answer was because if i kept doubling a it would cost more so the answer is a.

Summary: I learnt that you need to keep trying this question and test different possibilities.
