1.Calculate Puan Rohana's monthly cash flow
IRINA_888 [86]

Answer:

Step-by-step explanation:

Puan Rohana's income = Active income + passive income

                                     = 2000 + 450

                                     = RM 2450

Expenses = 1680 + 400

                 = RM 2080

Total expenses increased by 40%

New expenses after 40% increase = 2080 + 40% of 2080

                                                         = 2080 + (0.4 * 2080)

                                                          = 2080 + 832

                                                          = RM 2912

Puan Rohana's expenses is more than there income
