SOLUTION:

LESSON 2: SIMPLE & COMPOUND INTEREST

The simple interest formula : La= PRT;

The compound interest formula: A2- P(1 + R)', '7

in which, the multiplying factor (1• R), is called

a growth factor if it is greater than 1; otherwise, Ts called a decay factor,

EXAMPLE 1: If $160 amounts to $löd in 3 months, simple

interest, find to what it will amount in 1 yr. at the same rate of interest. princinal $160

SOLUTION

the Interest for 8

the rate of interestionthy = $166-$160 = $67

Hence, the interest for 1 yr. is $9.

And, the amount after 1 yr, is $160+$9= $1690

NOTE: We can have the value without finding the rate.

Since the rate is constant::

the interest in 6 months is 166-$160 - 60 the interest in 12 months is 12 of 66 = 69 the amount after 1 yr: is $360 + $99 $169

FEXAMPLE. 2: A certain sum of money at compound interestw

amounts in two years to $800 and in three years to $832. Find the sum of money Let it be the rate of interest on the princ.#P! Then, in 2 yr., the amount $800 - $P(1+R) ....... (a).

EXAMPIE 3: A steel ball is let fall from a height of 1500

and after each impact on the floor rises 3/4 of the height from which it fell. how high: does it rise after hitting the floor for the eighth time

SOLUTION

After each impact on the floor, the steel) rises 3/4 of the former ht. Hence, we can solve this problem by the compound interest formula, f = P(1,R)、 Of which,

the rate of rise 3/4 is equivalent to decrease 1/4 of the height. 1,e, R = 1/4 the original ht, 151 equiv. to the princ. the no. or times (8) 親 Hence, the ht. after the 8th hitting is:
