A: $0.63
B: $0.06
C: $0.78
D: $7.80

To find the sales tax, we need to calculate 6% of the total cost of the movie.

First, convert 6% to decimal form by dividing by 100: 6% / 100 = 0.06.

Then, multiply the sales tax rate by the total cost of the movie: $13.00 * 0.06 = $0.78.

Therefore, Ray paid $0.78 in sales tax, which is answer choice C.
