Well, whoever "arranged" the problem simply didn't know what he/she was doing...
IF the payment is 73.80 and the rate is 15.99% annual cpd. monthly,
then what is owing after 6 months is THE ACTUAL BALANCE OWING AFTER 6 PAYMENTS:
MONTH PAYMENT INTEREST BALANCE
0...
Sorry, but that problem as stated does not make sense.
Can you ask someone familiar with English to help you post it properly? Thank you.
Important is the rate: is it 15.99 annual effective, or .1599/12 monthly.
You are using nice round amounts:
expenses 125,000
revenue 200,000 and 300,000
sell for 400,000
...But start off with purchase of 510,074.04 !
Why is purchase such a silly amount ?
A circle is inscribed in a square with sides = 40.
A smaller (of course!) circle tangent to the above
circle and 2 sides of the square is inscribed in
one of the corners of the square.
What is the diameter of this circle?
No idea why you'd want to do that(!), but here goes:
(changing 1 meter to centimeters to make it more readable)
1 meter = 100 cm = diameter
circumference = π * d = ~314.16 (π = pi = ~3.1416)
314.16 / 78 = ~4.03
Hope that helps you...
