The experienced window washer can wash all the windows in Mike’s house in 2 hours, which implies that in 1 hour he completes 1/2 of the job.
By the same logic, the new trainee completes 1/7 of the job in one hour.
If they work together, they complete
of the job in one hour, meaning that they complete the job in 14/9 of a hour.
79 dollars divided by 50 pounds equals 1.58 so he made 1.58 dollars for every 1 pound so for question 10 thomas traded 160 pounds so 160 times 1.58 which equals 252.8 and for question 11 we just answered it to get question 10. question 10 is ~~$252.8~~ and question 11 is ~~$1.58~~
