Answer:

  The sale price is 90% of the original price.

Step-by-step explanation:

The original price is 100% of the original price. If 10% of the original price is subtracted, the new price is 100% - 10% = 90% of the original price.

The sale price is 90% of the original price.

__

s = 0.90×p

p = s/0.90 = 6.30/0.90 = 7.00

The original price of a ticket was $7.00.
