A teacher invested $600 in an account that paid 2% annual simple
interest. The teacher did not make any additional deposits or
withdrawals.
What is the total amount of interest paid by this investment at the end of
3 years?

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
