Question

jaffar bought 5 books. the prices of 4 of the books are $15, $16, $17, and $19. the average he paid for the 5 books is $17. how much did he pay for the fifth book?

Answer 1

Answer:

• $18

-----------------------

The average price Jaffar paid for the 5 books is $17.

To find the total cost of the 5 books, we multiply the average price by the number of books:

• $17 * 5 = $85

Now, we'll add up the prices of the first four books:

• $15 + $16 + $17 + $19 = $67

Finally, we'll subtract the sum of the first four books from the total cost to find the price of the fifth book:

• $85 - $67 = $18

So, Jaffar paid $18 for the fifth book.
