Question

Serena is taking 4 friends on a trip with her to Louisiana for spring break. They take two cars to the airport where Serena pays $7.00 per car to park. Serena is charged a total of $2114.00 for tickets and parking. She pays the same price for each plane ticket. Using an equation to help you solve, what was the price of each person’s ticket?

Answer 1

$420

Explanation:

number of people = 5 (4 friends + serena)

number of cars = 2

cost of parking = 7 for each car = 7 * number of cars = 7 * 2 = 14

let t be the cost of each ticket

cost of tickets = t for each person = t * 5

total cost = cost of parking + cost of tickets

= 14 + t * 5

= 2114

2114 = 14 + 5t

subtract 14 from both sides to isolate the variable and its coefficient

2100 = 5t

divide both sides by 5 to isolate t

t = 2100/5 = 420
