Help this is due very soon!! George purchased a concert ticket on a web site. The original price of
the ticket was $85. He used a coupon code to receive a 15% discount. The
website applied a 10% service fee to the discounted price. George's ticket
was less that the original price by what percent?
15%
10%
6.5%
8.5%

15 percent

Step-by-step explanation:

i would go for 8.5 since it was 85 right

Step-by-step explanation:

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
