Answer:
$ 9.99 almost $ 10 she would save every week.
Step-by-step explanation:
Weekly Salary = $ 628
Tax deduction= $149.8
Superannuation Fund = 4.5 % of $ 628= $28.26
Mortgage = 8 % of 628= $ 50.24
Income after deductions = $ 628- $ 149.8 - $ 28.26- $ 50.24= $ 399.7
10 % of $ 399.7 = $ 39.97 almost $ 40
In one week she would save $39.97/4= $ 9.99 = $ 10
