A test score of 90% is 63 points out of 70.
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
The amount if $2950 is invested at an annual rate of 8.4% compounded quarterly is $3486
<h3>
Compound interest</h3>
Compound interest is given by:

where t is the period, r is the rate, P is the initial amount, A is the final amount and n is the times compounded.
Given P = 2950, r = 0.084, n = 4, t = 2, hence:

The amount if $2950 is invested at an annual rate of 8.4% compounded quarterly is $3486
