In this unit we learned about percentage, precent change, and how to convert from decimal to fraction, fraction to precent, precent to decimal, etc. We also learned how to calculate precent change, or the amount that we will save.
We ended with a project with calculating which is better buy, and I did on a Christmas tree on Amazon with a fairly equal prize to make it a fair comparison. We have to calculate how much is the discount rate, how much is the discount, the amount of tax that me need to pay and compare the final price to find which one is the cheapest after all the discount and sale tax.
