You can build a dog house in 6 hours. And you work 8 hours how long would it take you to build 10 dog house.

So if you work for 8 hours everyday and you could build one dog house in 6 hours. Day one: 1 dog house. Day two: 2 dog houses. Day 3: 4 dog houses because you worked and extra 2 hours. Day 4: 5 dog houses. Day 5: 6 dog houses. Day six: 8 dog houses same reason as day 3. Day 7: 9 dog houses. Day 8: 10 dog houses. It would take 8 days to build 10 dog houses. Or 7.5 since you worked extra hours

Seven days and a half

For you work 8 hours a day

It takes you 6 hours to per each

You wanna make 10

10 by 6 is 60 on 8 = 7.5

Best luck!
