A college is selling tickets for a winter fund-raiser. One day, krissa sold 14 adult tickets and 8 student tickets for a total of $376. The next day, she sold 7 adult tickets and 11 student tickets for a total of $272. Krissa wanted to find the price of one adult ticket, a, and the price of one student ticket, s. She wrote and solved the following system of equations. 14 a + 8 s = 376. 7 a + 11 s = 272. She found that the price of one student ticket is $20 and the price of one adult ticket is $12. Which statement explains krissa’s error? she switched the prices of the tickets. The solution works in both equations. She did not write the correct system of equations. The solution only gives the correct price for one student ticket.
