1+4=5 2+5=12 3+6=21 8+11=?

Answers

40. This is because:
1+4= 5.
2+5= 7. Now you must take the 5 from the previous answer and add it to your new answer, which then gives you 12.
Now 3+6=9. Take 12 and add it to 9, which will give you 21. Follow the pattern to get the next answer, which is 40.

A man buys a book for $20 and wishes to sell it. What price should he mark on it if he wishes for a 40% discount and 50% profit on the cost price. Please explain your answer!

Answers

With that particular larcenous scheme in mind, he will price the book
regulaly at $50 .   See the price-tag in the attached picture.

With a regular price of $50 written all over it, he can run a spectacular,
once-in-a-blue-moon, "40%-off" sale.

   40% of $50 = 0.4 x $50 = $20 off

   $20 off of $50 ===> Sale price = $30 is what the buyer will pay
during the spectacular sale.

Then, the sale price of $30 is (30/20) = 1.50 of his own original cost.

1.50 of his own cost means 0.50 = 50% more than he paid for it.

Okay so I don’t get this at all

Answer: A

Explanation: The mean is when you add all the numbers and divide it by how many numbers their are. Since the graph is skewed it's best that we take the mean of the data set instead of the median. The 3 points on the ten point are outliers.

Hope This Helped! Good Luck!

A. Mean, because the data is skewed and there are outliers.
