Answer: $ 729.00864 can be saved per month.
Explanation:
Since, the total monthly income = $ 2,847.69
Fixed expenses = 36% of the total monthly income
= 36% of 2847.69
= 0.36 × 2847.69
= $ 1,025.1684
Thus, the discretionary monies = Total income - Fixed expenses
= 2,847.69 - 1,025.1684 = $ 1822.5216
Hence, Total saving = 40% of the discretionary monies
= 40% of 1822.5216
= 0.40 × 1822.5216
= $ 729.00864
⇒ We can save $ 729.00864 per month.
