5x^2 + 12x + 2 = 5(x + 6/5)^2 - 26/5
The axis of symmetry is x = -6/5.
The number of years is 4.781 in which $21,136.18 amount to $75,514.55 at 27.54% per annum when compounded quarterly and this can be determined by using the formula of the compound interest.
Given :
- Principal amount = $21136.18
- Final amount = $75514.55
- Interest rate per annum = 27.54%
- Compounded quaterly.
The formula of the compound interest is given by:

where A is the final amount, P is the principal amount, r is the interest rate, t is the time in years, and 'n' is a number of times interest applied.
Now, substitute the values of known terms in the above formula.


Now, take the log on both sides.

19.1237 = 4t
t = 4.781 years
Therefore, the correct option is B).
