Remark
Triangle BAC is isosceles. It has 2 sides that are both radii of the circle. I assume that C is the center of the circle.
Givens
AC = BC Both of these are radii.
<BCD = 20o Given
<A and <B are equal Both are opposite a radii of the circle
C is the circle's center Assumed otherwise we can't do it.
Solution
<BCD is an exterior angle of Triangle ACB It's on the same straight line as D and A
The sum of 2 remote interior angles = the sum of the exterior angle.
BAC = ABC Stated above
BAC + ABC = 20 Stated right above.
2BAD = 20
BAD = 20/2
BAD = 10

Log₄8 + 3 · log₄x
so the easiest way to do this is to note that these logs are separated by an addition symbol--it isn't "log₄8 + 3" times "log₄x"
log₄8
plus
3 · log₄x
for the second log, you can condense it with log properties/rules: the coefficient out front, when you condense it, becomes the exponent for the argument of your log:
3 · log₄x = log₄(x³)
so, having condensed that, your equation reads:
log₄8 + log₄(x³)
you could technically evaluate the first log, but the question wants both of these to become a single logarithm, which means you want to combine them. log properties state that if logs are being added, you can multiply their arguments (for example: logₓab = logₓa + logₓb)
you just want to apply that property to this, so you'll be multiplying your arguments 8 and x³:
log₄(8x³) is the answer, expressed as one logarithm.
Let's see... 6% of 14.50 is 0.87. 6% of 12 is 0.72. So...
14.50 + 87 = 15.37
12 + 0.72 = 12.72
15.37 + 12.72 = 28.09
Altogether, they paid $28.09
