Question

HELP I WILL GIVE 100 POINTS!!! NO FAKE ANSWERS, PLEASE ANSWER ALL PARTS!!

Answer 1

option 1 is not linear because it does not change by the same amount every year. It does not have a constant slope.

option 2 increases by 100 per year, constant slope, straight line, linear

-----------------------

a = A y^n

1100 =A y

1210 = Ay^2

1331 = A y^3

---------------

1210/1100 = y = 1.1

check 1331/1210 = y = 1.1 sure enough

1100 = A (1.1)

A = 1000

so

a = 1000 * 1.1^n

and the linear option 2

a = 1000+100n

You can put the numbers in for part C

10% compounded is better than 10% simple :)
