Carly is trying to get in shape to try out for the soccer team. She starts by running 2 miles a week. The second week, she runs twice as long plus 3 extra miles per week. The third week she runs 9/7 as much as she ran the second week. The week after that, she sprains her ankle and has to reduce her running time by 5 miles per week. How many miles did she run the week she was injured?
Let's think: First find how long Carly runs the second week: 2 miles * 2 + 3 = 7 miles. Then find how long she runs in the third week: 9 / 7 * 7 miles = 9 miles. Then subtract the 5 miles reduction from when she was injured: 9 miles - 5 miles = 4 miles.. The answer is: 4.

Emma bought a loaf of bread that had a certain number of slices. Her little cousin Andy ate 3 slices from the bread at two different points in time, and then Emma decided she would make toast with the remaining slices. If she uses 2 slices of bread to make 1 piece of toast bread, how many slices were in the original loaf if she was able to make 10 pieces of toast bread and had 1 slice of bread left?
Let's think: Little Andy ate 3 slices 2 times giving a total of 3 * 2 = 6 slices of bread. 1 piece of toast bread requires 2 slices of bread so 10 pieces need 10 * 2 = 20 slices of bread. There is 1 slice of bread left so in total there were 6 + 20 + 1 = 27 slices of bread in the loaf.. The answer is: 27.

Bonnie and Samuel went to the market together. Bonnie bought 8 apples. Samuel bought 20 more apples than Bonnie. Samuel then ate half of them and used 1/7 of them to make apple pie. How many apples does Samuel have left?
Let's think: Samuel bought 20 + 8 = 28 apples. Samuel ate 28 / 2 = 14 apples. Samuel used 28 / 7 = 4 to make apple pie. Samuel has 28 - 14 - 4 = 10 apples left.. The answer is: 10.

Mr. Johnson is organizing the school Christmas play and needs 50 volunteers to help with decorating the auditorium. 5 students from each of the school’s 6 math classes have volunteered to help. 13 teachers have also volunteered to help. How many more volunteers will Mr. Johnson need?
Let's think:
Since 5 students from each of the 6 math classes have volunteered, there are 5 * 6 = 30 total student volunteers. In addition to the 30 student volunteers, 13 teachers have also volunteered so there are 30 + 13 = 43 total volunteers. Mr. Johnson needs 50 volunteers and currently has 43 volunteers, so he needs 50 - 43 = 7 more volunteers.. The answer is: 7.
