It takes 15 mink skins to make a coat. Andy buys 30 minks and each mink has 6 babies, but half the total minks are set free by activists. How many coats can he make?

How many minks are there? ** First find the total number of baby minks: 30 minks * 6 babies/mink =

<<30*6=180>>180 minks How many minks are there? ** Add this to the number of adult minks: 180 minks + 30 minks = <<180+30=210>>210 minks How many minks are set free? ** Then divide this number in half to find how many aren't set free: 210 minks / 2 = <<210/2=105>>105 minks How many coats can Andy make? ** Then divide the remaining number of minks by the number of minks per coat to find the number of coats: 105 minks / 15 minks/coat = <<105/15=7>>7 coats #### 7 A used car lot has 24 cars and motorcycles (in total) for sale. A third of the vehicles are motorcycles, and a quarter of the cars have a spare tire included. How many tires are on the used car lot’s vehicles in all? How many motorcycles are there? ** The used car lot has 24 / 3 = <<24/3=8>>8 motorcycles with 2 tires each. How many cars are there? ** The lot has 24 - 8 = <<24-8=16>>16 cars for sale How many cars have a spare tire? ** There are 16 / 4 = 4 cars with a spare tire with 5 tires each. How many cars have 4 tires? ** The lot has 16 - 4 = <<16-4=12>>12 cars with 4 tires each. How many tires are on the used car lot’s vehicles in all? ** Thus, the used car lot’s vehicles have 8 * 2 + 4 * 5 + 12 * 4 = 16 + 20 + 48 = <<8*2+4*5+12*4=84>>84 tires in all. #### 84 Samuel bought 2 dozen doughnuts and Cathy bought 3 dozen doughnuts. They planned to share the doughnuts evenly with their 8 other friends. How many doughnuts will each of them receive? How many doughnuts does Samuel have? ** Since 1 dozen is equal to 12, then Samuel has 2 x 12 = <<24=24>>24 doughnuts. How many doughnuts does Cathy have? ** While Cathy has 3 x 12 = <<3*12=36>>36. How many doughnuts do Samuel and Cathy have together? ** They both have 24 + 36 = <<24+36=60>>60 doughnuts together. How many friends will share the doughnuts? ** There are 8 friends + 1 (Samuel) + 1 (Cathy) = <<8+1+1=10>>10 that will share the doughnuts. How many doughnuts will each of them receive? ** Thus, each of them will get 60/10 = <<60/10=6>>6 doughnuts. #### 6 Laura is planning her wedding.

They use a mixture of pitch and gravel to make the asphalt to pave the road. Each truckloads of asphalt uses two bags of gravel and five times as many bags of gravel as it does barrels of pitch to make. It takes three truckloads of asphalt to pave each mile of road. The company paved 4 miles of road on one day, then one mile less than double that on the second day. How many barrels of pitch will the company need to finish the remaining road on the third day? How many miles did the company pave on the second day? ** On the second day, the company paved 4 * 2 - 1 = <<4*2-1=7>>7 miles. How many miles of road remain to pave? ** The company has 16 - 7 - 4 = <<16-7-4=5>>5 miles of road remaining to pave. How many truckloads of asphalt will the company need to pave the remaining 5 miles of road? ** They will need 3 * 5 = <<3*5=15>>15 truckloads of asphalt to pave 5 miles of road. How many bags of gravel will the company need to pave the remaining 5 miles of road? ** For 15 truckloads, they will need 15 * 2 = <<15*2=30>>30 bags of gravel. How many barrels of pitch will the company need to finish the remaining road on the third day? ** Thus, the company will need 30 / 5 = <<30/5=6>>6 barrels of pitch to finish the road on the third day. #### 6 Dorothy earns $60000 a year from her work.
