[Question]Jack needs to mop the bathroom and the kitchen. If the bathroom floor is 24 square feet and the kitchen floor is 80 square feet, and Jack can mop 8 square feet per minute, how many minutes does he spend mopping?
[Answer]First find the total floor area Jack needs to mop: 24 sq ft + 80 sq ft = 104 sq ft. Then divide the total area that needs to be mopped by Jack's mopping rate: 104 sq ft / 8 sq ft / minute = 13 minutes. The answer is 13.
Q: A small, old, wooden bridge can hold up to 100 kilograms at once. Mike, Megan, and Kelly are three children who decided to cross the bridge at the same time. Kelly weighs 34 kilograms, which is 15% less than Megan. Mike weighs 5 kilograms more than Megan. How much too much do the three children weigh together to cross the bridge?
A: If Kelly weighs 15% less than Megan, this means Kelly's weight is 100 - 15 = 85% of Megan's weight. 85% is 0.85, so Megan weighs 34 / 0.85 = 40 kilograms. Mike weighs 5 kilograms more than Megan, so he weighs 40 + 5 = 45 kilograms. In total all three kids weigh 34 + 40 + 45 = 119 kilograms. That means to cross the bridge safely, they weigh 119 - 100 = 19 kilograms too much. The answer is 19.
Question: Daisy's Flower Shop sold 45 daisies on its first day. On their second day, they sold 20 more flowers than they did on their first day. On the third day, they sold 10 less than twice the flowers that were sold than on the second day. If the flower shop sold a total of 350 daisies for 4 days, how many daisies were sold on the 4th day?
Answer: The flower shop sold 45 + 20 = 65 daisies on the second day. Twice the number of flowers on the second day is 65 x 2 = 130. So, the flower shop sold 130 - 10 = 120 daisies on the third day. The total daisies sold for 3 days was 45 + 65 + 120 = 230. Therefore, 350 - 230 = 120 daisies were sold on the 4th day. The answer is 120.

Q: Amelia has laundry to do. She has a load of whites that will take 72 minutes in the washing machine and 50 minutes in the dryer. She has a load of darks that will take 58 minutes in the washing machine and 65 minutes in the dryer. She has a load of colors that will take 45 minutes in the washer and 54 minutes in the dryer. If she does one load at a time, how long will it take her to wash and dry all three loads, in minutes?
A: It will take her 72 minutes in the washer + 50 minutes in the dryer = 122 minutes for the whites. It will take her 58 minutes in the washer + 65 minutes in the dryer = 123 minutes for the darks. It will take her 45 minutes in the washer + 54 minutes in the dryer = 99 minutes for the colors. Altogether, it will take 122 minutes for whites + 123 minutes for darks + 99 minutes for colors = 344 minutes to do the laundry. The answer is 344.
Question: John buys 2 packs of gum and 3 candy bars. Each stick of gum cost half as much as the candy bar. If the candy bar cost $1.5 each, how much did he pay in total?
Answer:
The gum cost $1.5 / 2 = $.75 per pack. So he pays $.75 * 2 = $1.5 for the gum. He pays $1.5 * 3 = $4.5 for the candy bars. So in total, he pays $1.5 + $4.5 = $6. The answer is 6.
