# Percentage Unit Reflection

Why doesn’t 20% discount followed by a 20% markup get you back to where you started?
After you make a 20 percent discount, that amount is being marked up by 20 percent, so it is impossible for you to get back where you started. For example, there is a 20 percent of from 100, that will be 100x(1-20%)= 80, and then 80 is marked up by 20 percent, not 100 therefore,20% discount followed by a 20% markup won’t get you back to where you started.

How do companies make a profit?
Companies make profits by selling the product by increasing the cost. Some of the companies increases their profit by doing promotions and giving out coupons which can attract many customers but is totally useless.

Is it possible for everyone to win in the marketplace?
It is not possible for everyone to win in the marketplace because things are inflating. The cost(employees, materials for the product) cost more and more every year and then you’ll have to sell the product in a high cost that customers might think that its not worth buying it. But if they lower the price of the product, the company couldn’t make profit and there might be a bankruptcy.

# Mathematics Assessment

After the Managing mark-up assessment, I have learnt how the company sells the product that could earn the biggest amount of money, for example giving out useless coupons(buy \$5 off good for any purchase over 50 dollars or more) that would trick the customers into buying more of its product. From then the company could increase its profit.I have also learnt how the company would have a contingency planning and therefore, I have now become a more educated investor. I now know how to buy things with the lowest cost and I won’t get ripped off by companies. I now know how to choose a bank that would let us earn more in a short period. I would put a big amount of money from the very beginning so as that when I grow up, I could get the money out for university use. before I did this math assessment, I didn’t know much on how to find the profit that a company can earn, making tables and let excel do the math for me.After the assessment, I only need to enter the datas and can easily ask excel to do all the calculations. I started to get familiar on calculating the profit that the company earn with the formulas, gather the information and make a graph and compare it with the other.
