You can put this solution on YOUR website!
Uniform rates work or job rule is RT=J, for rate time job.
The rate in these situations should be understood as unit of JOB per TIME.

________________rate_________time_________job
Jasmine_________1%2F12__________12___________1
Crystal__________1%2Fx__________x____________1
Together________1%2F8___________8____________1

What is really important is that you are finding information about the rates. The two agents working together are working at the SUM of their individual rates. Note how time for Crystal to do 1 job has been assigned x number of hours.

highlight_green%281%2F12%2B1%2Fx=1%2F8%29
Solve for x.
