Problems involving financial transactions is the first topic we went over today.

Here we talk about profit (selling price – cost) and profit percentage (profit / cost), discounted price (usual price – discount percentage * usual price), interests. This is mainly the continuation of what we learned last week, about rate, ratio and percentage.

We move on to coordinate plane and representing ordered pairs in the coordinate plane, drawing graphs for linear equation with two variables, and how to use linear graph to solve simple problems.
