Here,
Time: 4 years
Rate: 5%
Simple interest:500$
So, principal:?
We know,
SI=P*T*R/100
500=P*4*5/100
500=20P/100
20P=50000
P=50000/20
P=2500$
So 2500$ is needed to make atleast 500$ interest in 4 years with 5% rate

Step-by-step explanation:
Use formula

where
I = interest,
P = principal,
r = rate (as decimal),
t = time (in years).
In your case,

Substitute:

A) (1 x 4) + (1 x 4) = 8
There are 8 possible combinations
B) RH:RD:RC:RS:BH:BD:BC:BS
Hope this helps and have a nice day!
