20.99%/12 = 1.7492% which is the monthly rate (or at least the way my credit card does it)
1.7492/100 * 3825 = 66.91
66.91 is just a rounding error. <<<=== answer.

Let's solve for C in the equation:
Answer:
Step-by-step explanation:
-2x² + 12x + 32 = 0
discriminant = 12² - 4(-2)(32) = 400
positive discriminant means there are two distinct real roots
x = [-12 ± √(12² – 4(-2)·32)] / [2·(-2)]
= [-12 ± √400] / (-4)
= [-12 ± 20] /(-4)
= 8, -2
