Let’s use the variable p for the total amount of money you make.
First off, p= 5.5t + 10 for the babysitting job. Technically, that is all the work you can possibly have.
Secondly, p= 10h for the coffee shop job, with h being a separate amount of time than the variable t due to the fact that the are attributed to different jobs.
Lastly, p= 5.5t + 10h + 10 for both jobs during the entire day, with the hours worked being applied separately from each job.
