Answer:
22.25
Step-by-step explanation:
Let the original price of the book be x. If, after a 33% markup on the initial price, the student had to pay 115.00 for it, then we can calculate x as:
(1 + 33%)(x) = 115
1.33x = 115
x = 115/1.33 = 86.47
This means that the bookstore paid $86.47 for the book.
If you would like to know how much is 68% of 12, you can calculate this using the following steps:
68% of 12 = 68/100 * 12 = 816/100 = 8.16
Result: 68% of 12 is 8.16.

Time taken by the submarine to reach the cave is 10 seconds.
Step-by-step explanation:
We are given that,
The elevation of the underwater cave = -120 feet.
The rate at which the submarine descends to the cave = -12 feet per second
Thus, we have,
The time taken by the submarine to reach the cave = 
= 10 seconds.
Hence, the time taken by the submarine to reach the cave is 10 seconds.
