Amanda has to sell 80 tickets in 3 days so she can make enough money to go on vacation. On the first day, she sells 5 of her friends 4 tickets each. On the second day she sells 32 tickets. How many tickets does she need to sell on the third day to meet her goal? Give me reasons, before answering the question
Amanda sells 4 tickets to 5 friends so she sells 4 * 5 = 20 tickets on her first day. On her second day, she sells 32 tickets for a total of 20 + 32 = 52 Tickets so far. Having 80 tickets as the goal, she needs to sell 80 - 52 = 28 Tickets on her last day. So the final answer is 28.
