+34 Hello. I am in need of assistance with this question. I am familiar with how to convert percentages into decimals and what not, but this question is really confusing to me. Any help? It would be much appreciated!
Max bought two items that were both on sale. One item was 10% off and one item was 20% off. Max says that he saved 15% altogether. Is he correct? Explain your answer above? Is Max correct? Why or why not? How did you reach your conclusion?
It all depends on the original price of the 2 items. If they were equal in price, then your friend is right. The percentage he saved is simply the average of the two: [10 + 20] / 2 = 15%.
If the prices of the 2 items were radically different from each other, then the average would be quite different as well. Take 2 items priced at 100 dollars and 1,000 dollars. For the first one, he would simply pay 90 dollars, and for the second he would pay 800 dollars. Now you add up what he paid: 90 + 800 =890 dollars. Divide what he paid by the original price of the items: 890 / 1,100 =80.90% of the original price. Therefore, he saved: 100% - 80.90% =19.10% on the 2 items. Do you understand it now?

Try it with a few examples and see what happens.
Maybe try
1) they are both $10 before the discount
2) the 10% off one was 10 dollars and the other one was 20 dollars
3) the 10% off one was 20 dollars and the other one was 10 dollars
Work out the savings for each one and see it it is 15% or more, or less than the original total.
See if you can do it by yourself now. But if you really don't get it then say so.
(Think about it properly yourself first though)
