Six friends are planning to attend a concert. If another friend also goes with them, they will get a group discount on their tickets. If the new total price of the tickets with the group discount is the same as the original total price of the tickets without the group discount, how much is the discount? Choose the correct choice from the following answers.
A) 11%	B) 14%	C) 20%	D) 22%	E) 26%
Let x be the original price of one ticket.   The total original cost is 6x.   The new cost is 7y, where y is the discounted price of one ticket.   6x = 7y   y = 6x/7 which is about 0.86x which is a discount of about 14%.   The answer is 14%.
