Answer: Liza invested $15000 at 3% and $30,000 at 4%
Step-by-step explanation:
Let x be the amount invested by Liza at 3% interest then the amount she invested in 4% interest will be 2x.
We know that the compound interest with principal P is give By
, where n is the number of period.
Now, interest earned in 3% (in decimal 0.03) account in 1 year is given by:-
Similarly, interest earned in 4% (in decimal 0.03) account in 1 year is given by:-
According to the question,
Also, 2x=2(15000)=30000
Therefore, Liza invested $15000 at 3% and $30,000 at 4% .

Answer:
14.4 miles
Step-by-step explanation:
Given that :
Distance moved North = 12 miles
Distance moved West = 8 miles
Shortest distance to reach starting point :
Let shortest distance to reach starting point = d miles
Using the relation :
Longest side of a right angled triangle:
d = sqrt(8^2 + 12^2)
d = sqrt(64 + 144)
d = sqrt(208)
d = 14.422205
d = 14.4 miles (nearest tenth of a mile)
