tina is saving to buy a notebook computer. she has two options. the first option is to put $400 away
initially and save $20 every month. the second option is to put $200 away initially and save $40 every
month. after how many months would tina save the same amount using either option? how much
would she save with either option?
after
tina will save $
with either

Month 10

If you do 400 + (20 x 10) you get 600

If you do 200 + (40 x 10) you get 600

Hope this helps!

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)
