1) 11:20 You can represent the price of coffee as the variable x. The donut would equal x +1 since it cost 1 dollar more than the coffee. The total amount they’re worth together is 23.40 so x + (x + 1) = 23.40. x = 11.20, meaning the coffee costs $11.20 and the time of the crime was 11:20 2) 11:20 Elijah lives 2 houses down from Kaya since Kaya’s house number is 227 and Elijah’s is 225. This means that there is 1320 x 2 = 2640 feet between their homes. 2640/5280 = 0.5 miles. Use the equation Time = Distance/Speed to find that it took him 0.5/1.5 = 0.333 hours to get to Elijah’s house. 0.333 x 60 = 20 minutes. Since he started at 11:00 he arrives at 11:20 3) 10:40 Lee worked for 3 hours between 9:00 and 12:00. This means he worked 5 hours in his second shift. Since the second shift started at 5:00 he finished working at 10:00. It takes him 40 minutes to get home so he arrived home at 10:40. This is after 10:30 so he goes to sleep immediately at 10:40 4) 11:21 10 hundreds equals 10 x 100 = 1000. 11 tens equals 11 x 10 = 110. The answer is therefore 1000 + 110 + 11 = 1121 so the time is 11:21 5) Jay It is Jay as he was shown to be at Elijah’s house at 11:20 based on his fitness watch and everybody else was sleeping or at home.
