Question: Tom was putting hardwood flooring into his living room that measured 16' long and 20' wide. The flooring comes 10 sq ft per box and he has already put down 250 sq ft of flooring. How many more boxes does Tom need to complete the job?
Answer: The entire sq ft of the living room is LxW so the room is 16x20 = 320 sq ft. Tom has already put down 250 sq ft so he needs to put down 320 - 250 = 70 sq ft of flooring. The boxes contain 10 sq ft of flooring per box and he needs 70 more sq ft of flooring so he needs 70 / 10 = 7 more boxes. The answer is 7.

Question: Aren’s flight from New York to Hawaii will take 11 hours 20 minutes. He spends 2 hours reading, 4 hours watching two movies, 30 minutes eating his dinner, 40 minutes listening to the radio, and 1 hour 10 minutes playing games. How many hours does he have left to take a nap?
Answer: The flight from NY to Hawaii will take 60 x 11 + 20 = 680 minutes. All the activities will take 120 + 240 + 30 + 40 + 70 = 500 minutes. For his nap, he has 680 - 500 = 180 minutes. To convert minutes to hours, he has 180 / 60 = 3 hours. The answer is 3.

Question: Anna wears a size 2. Her friend Becky wears a size three times larger than Anna's. Ginger wears a size twice Becky's size minus 4. What size does Ginger wear?

Question: Carly is making burgers for a neighborhood BBQ. Each burger needs to be cooked for 4 minutes on each side. Carly can fit 5 burgers on the grill at once. If half her 30 guests want 2 burgers and the other half each want 1, how long will it take Carly to cook all the burgers?
Answer:
First find half the number of guests at Carly's party: 30 guests / 2 = 15 guests. Then multiply that number by 2 for the number of burgers half the guests want: 15 guests * 2 burgers / guest = 30 burgers. Then add the 15 burgers for the 15 guests who only want 1 to find the total number of burgers: 30 burgers + 15 burgers = 45 burgers. Then divide the total number of burgers by the number of burgers Carly can cook at once to find the number of batches she cooks: 45 burgers / 5 burgers / batch = 9 batches. Then multiply the number of sides per burger by the cooking time per side to find each burger's total cook time: 4 minutes / side * 2 sides = 8 minutes. Finally, multiply each batch's cook time by the number of batches to find the total cook time: 8 minutes / batch * 9 batches = 72 minutes. The answer is 72.
