The first book you select can be any one of 700.

. . . For each of those ...

The second book can be any one of the other 699.

. . . For each of those ...

The third book can be any one of the remining 698.

The total number of ways to gather three books from the shelves into your hands is  (700 · 699 · 698)  =  <em>341,531,400 ways</em> .

Your bank granted you a single payment loan of 2,500 for 90 days at 10 percent interest. What is the interest on the loan?
viva [34]

Answer:

62.5 interest on 2500 loan

Step-by-step explanation:

Given that,

amount of loan bank has granted = 2500

number of years = 90 days

                              90 days   = 3 month

                              3 months = 1/4 year = 0.25 year

interest rate = 10%

                     = 10 / 100

                     = 0.1

Formula to use

Principal * interest rate expressed as a decimal * time in years

2500 * 0.1 * 0.25

62.5

Hence, the interest on the loan of 2500 with 10% interest rate for 90 days is 62.5
