Sheena is sewing the bridesmaid’s dresses for her sister’s wedding. She can sew one dress in 12 hours. There are 5 bridesmaids in the wedding. If Sheena sews the dresses 4 hours each week, how many weeks will it take her to complete them? Give the rationale and then the answer.
Let's think step by step. It will take Sheena 12 hours x 5 bridesmaids = 60 hours to sew the dresses. It will take her 60 hours / 4 hours = 15 weeks.. The answer is: 15.

Charles is jogging while listening to his favorite album. He runs at 6 MPH when he's got music on and 4 MPH when he doesn't. His album is 40 minutes long. How many minutes will it take him to jog 6 miles? Give the rationale and then the answer.
Let's think step by step. He runs at .1 miles per minute because 6 / 60 = .1. While the album is playing he can run 4 miles because 40 x .1 = 4. He has to run 2 miles without the album because 6 - 4 = 2. Without music he runs 1 / 15 miles per minute because 4 / 60 = 1 / 15. He will run the remaining 2 miles in 30 minutes because 2 / (1 / 15) = 30. It will take him 70 minutes in total because 40 + 30 = 70.. The answer is: 70.

On Friday, Markeesha sold 30 boxes of crackers for her scout troop's fundraiser. On Saturday, she sold twice as many as on Friday. On Sunday, she sold 15 fewer than Saturday. How many boxes did she sell over the three days? Give the rationale and then the answer.
Let's think step by step. On Saturday, she sold 2 * 30 = 60 boxes. On Sunday, she sold 60 - 15 = 45 boxes. She sold a total of 30 + 60 + 45 = 135.. The answer is: 135.
