Problema Solution
mina bought 2 plane tickets to new york city and used a coupon for 15% off the ticket price. the total cost of her tickets, with the discount, was 653.30. what equation could she use to find the price of the tickets, without the discount? how much was discounted off the tickets?
Answer provided by our tutors
let 'x' represent the price of a single ticket without the discount
653.30 = 2x - 0.15(2x)
solving for 'x' we have x=384.29
the original price was $384.29
2(384.29) - 653.30 = 115.28
the total discount was $115.28, or $57.64 per ticket
