Scorpion4ik [409]

Answer: the school paid $80 for the book.

Step-by-step explanation:

Let x represent the amount that the school paid for the book.

Her school charges a lost book fee equal to 75% of the cost of the book. It means that the amount that the school would charge on a book that cost $x is

75/100 × x = 0.75 × x = 0.75x

Sarah received a notice stating that she owed the school $60 for he lost book. It means that

0.75x = 60

x = 60/0.75

x = $80

A company wants to have $20,000 at the end of a ten-year period by investing a single sum now. How much needs to be invested in
Sergio039 [100]

Answer:

<h2>Principal is $6441.22 </h2>

Step-by-step explanation:

let us assume  the investment is compounded over the given period

Given data

Final amount A= $20,000

Rate r= 12%= 0.12

Time t= 10 years

principal=?

The compound interest formula is

A= P(1+r)^n^t

Substituting our given data we have

20000= P(1+0.12)^1^0\\20000= P(1.12)^1^0\\20000= P(3.105)\\

Dividing both side by 3.105 to find P

P=\frac{20000}{3.105} \\P= 6441.22

Principal is $6441.22
