Answer:~10.6667 days
Step-by-step explanation:
let x represent number of chairs installed per day.
so proportion can be set up as:
720/8=240/time
now you can solve
90=240/time
to find the time, rearrange the equation:
time= 240/90
time=~2.6667 days
To find the total time from start to finish, add the time it took to install the first set of chairs (8 days) to the time it will take to install the remaining chairs:
Total time=8+2.6667
Total time=10.6667 days
Total time=10.6667 days
So, it will take approximately 10.6667 days to install all the chairs from start to finish.
