To save a total of $540 Breanna need to save money for approximately 16 weeks.

Given that Breanna works in the mall and her hours increase during busy shopping times of the year and Breanna has a plan to save $25 each week for 5 weeks , then increase that amount by $20 for the next 7 weeks during the busy time, then go back to $25 per week.

We are required to find the total number of weeks that Breanna need to work to save a total of $540.

The equation showing saving of Breanna can be written as under:

5*25+7*45+25x=540

(x is the extra weeks for which she has to save the money)

Solving the equation for the value of x.

125+315+25x=540

440+25x=540

25x=100

x=4

Total number of weeks=5+7+4

=16 weeks

Hence to save a total of $540 Breanna need to save money for approximately 16 weeks.
