Two Real Life Situations:

1) You and your friend decided to go to a huge store called Target, because everything is 70% off. Your friend wishes to buy a very bright and pink shirt, which costs $60. How much money does she need to pay?

Answer:70% of 60 = 42. $42 is the discount. $60 - 42 (discount) = 18 dollars. So, your friend will buy the shirt for $18 instead of $60.

2) My family and I went to a restaurant and ate lunch. When we were finished, my father asked for the bill, and the waiter brought it. The price was $150. Since the waiter was so polite, we decided to give him a tip of 10%. How much money did we give in total?

Answer: 10% of $150 = 15. So, in total we gave $165.

Homework

                                How do you feel about Fractions, Decimals Percents?

Fractions,Decimals + Percentages are quite easy when you have a lot of practice. Ifeel like I have forgotten a lot about this, because I haven’t do it for wholesummer, but when I started doing some problems and catching up with the class,I started to realize that it is not that hard. The hardest part of this isturning Fractions into decimals; because this stage is when you make a lot ofmistakes. For example, I decided to make my own problem, and I made thestupidest mistake when simplifying 14/5. I put 15/5, so the whole problem was amistake. The next stage is easier because all you have to do is use the DUPE toturn the decimal into a percent.
