Answer :
Final answer:
To achieve her goal in a 10 week time frame, Sally should work 33 hours each week at the bakery and tutor for 8 hours.
Explanation:
This is a problem of linear algebra, which can be solved using a system of linear equations. Sally can work no more than 41 hours in a week, so this sets up our first equation: c + t = 41, where 'c' and 't' are the hours Sally works at the bakery and as a tutor respectively.
We also know that Sally needs to accumulate at least $755 in 10 weeks, which means she needs to make a minimum of $75.5 per week: 5t (tutoring income) + 8c (baking income) = 75.5, which builds our second equation.
The solution to these two equations will give Sally the optimal numbers of hours she should spend on each job. Simple linear algebra leads us to c = 33 (bakery) and t = 8 (tutoring). Therefore, Sally should ideally work 33 hours at the bakery and 8 hours as a tutor each week to meet her goal.
