An amusement park is installing a new roller coaster. The park intends to charge $5 per adult and $4 per child for each ride. It
hopes to earn back more than the $650,000 cost of construction in four years. With the best of weather, the park can provide 125,000 adult rides and 50,000 child rides in one season
Keeping the price and amount of people in mind, the answer is actually pretty easy to find. Just multiply 125,000 by 5, which equals 625,000 and 50,000 by 4, which equals 200,000, and add the products together to get $825,000 total income per season.
