You are given a choice of taking the simple interest on $100,000 invested for 4 years at a rate of 2% or the interest on $100,000 invested for 4 years at an interest rate of 2% compounded quarterly. Which investment earns the greater amount of interest? Give the difference between the amounts of interest earned by the two investments.

The second type of investment earns greater amount of interest.

Step-by-step explanation:

1)

SI = prt / 100

= 10000 x .02 x 4

= 8000

2)

At compound intetest

A = P(1 + r/n)^nt

= 108307.12

Interest = 108307.12 - 100000 = 8307.12

Difference

8307.12 - 8000 = 307.12

part a

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
