sarah lost her science book her school charges a lost book fee equal to 75% of the cost of the book sarah recieved a notice she owes the school $60 for the book how much did the school pay for the book

$80

Step-by-step explanation:

You have been told that Sarah ended up paying $60, and you were told before that the charge for a lost book was 75%.

Therefore

$60 = 75%

Now we have to find out what amount of money would be equivalent to 100%:

To do this, find out what amount of money would be equivalent to 25% first.

You can do this by dividing both values by 3.

60 / 3 = 20

75 / 3 = 25

So now $20 = 25%

Now find 100% (which is the original amount) multiply each value by 4 :

$80 = 100%

So the school payed $80 for the book.

hope this helps :)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
