Scheduled payments of $1400 due today and $1600 due with interest at 11.5% compounded annually in five years are to be replaced by two equal payments. The first replacement payment is due in 18 months and the second payment is due in 4 years. Determine the size of the two replacement payments if interest is 11% compounded quarterly and the focal date is 18 months from now.

idk what the heck he answer is, i’m just putting this here so i finish my account

hello there!

i believe the answer is

(cot2+1)/sec2=cot2

    csc2/sec2=cot2

  (1/sin2)/(1/cos2)=cot2

  (1/sin2)(cos2/1)=cot2

  cos2/sin2=cot2

  (1/tan2)=cot2

  (cot2)=(cot2)

hope this !

hyperz ^_^

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.

the answer is

a.

x = 42

y = 10

i got it down chief.
