Answer: $12
Step-by-step explanation:
The formula to calculate the compound interest , if the interest is compounded semi-annually :-
, where P = Principal amount
r = rate of interest ( in decimal)
t= Time ( in years)
Given : P= $1500
r= 1.6 % =0.016
t= 6 months =
year [∵ 1 year = 12 months]
Then, the interest earned by Robert in 6 months will be :-
Hence, Robert earned $12 as interest .

Answer:
n = 3.8
Step-by-step explanation:
0.3(n - 5) = 0.4 - 0.2n
Distribute
.3n - 1.5 = .4 - .2n
Add .2n to each side
.3n +.2n -1.5 = .4 -.2 +.2n
.5n -1.5 = .4
Add 1.5 to each side
.5n -1.5 +1.5 = .4+1.5
.5n = 1.9
Divide each side by .5
.5n/.5 = 1.9/.5
n =3.8
