Hey there!!
Basic formula :
... a² - b² = ( a + b ) ( a - b )
Equation given :
... 81x² - 25
... ( 9x )² - ( 5 )²
... ( 9x + 5 ) ( 9x - 5 )
Hope it helps!!
a) plug in x =2700 into the given equation and solve for y
b) plug in y = 43 into the given equation and solve for x
c) plug in y = 0 into the given equation and solve for x
hope this helps.
Answer:
15.84%
Step-by-step explanation:
There is no formula that will tell you the interest rate. It must be computed iteratively or found graphically. A financial calculator can do the work for you.
The parameters this one uses are
- number of payments (24)
- the amount financed (1925 -125 = 1800)
- the monthly payment, negative because it is being paid (-88.00)
- the remaining balance after all payments (0)
- the number of payments per year (monthly = 12)
- the number of times per year interest is compounded (monthly = 12)
